class=\"rk-lead\"\u003e\u003cspan class=\"rk-kw\"\u003eMagnet wire\u003c\/span\u003e — also known as \u003cspan class=\"rk-kw\"\u003eenameled copper wire\u003c\/span\u003e, winding wire, or enamel-coated copper wire — is a copper conductor covered by a thin, tough polymer film that lets thousands of turns sit side by side in a coil without short-circuiting. It is the fundamental conductor inside every motor, transformer, inductor, and electromagnetic device that converts electricity into motion, voltage, or magnetic force.\u003c\/p\u003e\n\u003ch2\u003eWhat Is Magnet Wire?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMagnet wire\u003c\/strong\u003e is an insulated electrical conductor, almost always copper (and sometimes aluminum), designed to be wound into tight coils. The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called \u003cstrong\u003eenameled wire\u003c\/strong\u003e or \u003cstrong\u003ewinding wire\u003c\/strong\u003e. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\u003c\/p\u003e\n\u003cp\u003eThe key difference between \u003cstrong\u003eenameled copper wire\u003c\/strong\u003e and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\u003c\/p\u003e\n\u003ch3\u003eThe Conductor: High-Purity Copper\u003c\/h3\u003e\n\u003cp\u003eThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\u003c\/p\u003e\n\u003ch3\u003eThe Insulation: Enamel Polymer Film\u003c\/h3\u003e\n\u003cp\u003eThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\u003c\/p\u003e\n\u003ch3\u003eHow Enameled Copper Wire Works in a Coil\u003c\/h3\u003e\n\u003cp\u003eWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns. The thinner and more consistent the insulation, the more copper fits into the same winding window — and the stronger, smaller, and more efficient the resulting motor, transformer, or solenoid.\u003c\/p\u003e\n\u003ch2\u003eTypes of Enamel Insulation\u003c\/h2\u003e\n\u003cp\u003eChoosing the right enamel chemistry is the most important decision when selecting magnet wire.

It is the fundamental conductor inside every motor, transformer, inductor, and electromagnetic device that converts electricity into motion, voltage, or magnetic force.\u003c\/p\u003e\n\u003ch2\u003eWhat Is Magnet Wire?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMagnet wire\u003c\/strong\u003e is an insulated electrical conductor, almost always copper (and sometimes aluminum), designed to be wound into tight coils. The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called \u003cstrong\u003eenameled wire\u003c\/strong\u003e or \u003cstrong\u003ewinding wire\u003c\/strong\u003e. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\u003c\/p\u003e\n\u003cp\u003eThe key difference between \u003cstrong\u003eenameled copper wire\u003c\/strong\u003e and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\u003c\/p\u003e\n\u003ch3\u003eThe Conductor: High-Purity Copper\u003c\/h3\u003e\n\u003cp\u003eThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\u003c\/p\u003e\n\u003ch3\u003eThe Insulation: Enamel Polymer Film\u003c\/h3\u003e\n\u003cp\u003eThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\u003c\/p\u003e\n\u003ch3\u003eHow Enameled Copper Wire Works in a Coil\u003c\/h3\u003e\n\u003cp\u003eWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns. The thinner and more consistent the insulation, the more copper fits into the same winding window — and the stronger, smaller, and more efficient the resulting motor, transformer, or solenoid.\u003c\/p\u003e\n\u003ch2\u003eTypes of Enamel Insulation\u003c\/h2\u003e\n\u003cp\u003eChoosing the right enamel chemistry is the most important decision when selecting magnet wire.

It is the fundamental conductor inside every motor, transformer, inductor, and electromagnetic device that converts electricity into motion, voltage, or magnetic force.\n\nWhat Is Magnet Wire?\n\nMagnet wire is an insulated electrical conductor, almost always copper (and sometimes aluminum), designed to be wound into tight coils. The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called enameled wire or winding wire. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\n\nThe key difference between enameled copper wire and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\n\nThe Conductor: High-Purity Copper\n\nThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\n\nThe Insulation: Enamel Polymer Film\n\nThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\n\nHow Enameled Copper Wire Works in a Coil\n\nWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns. The thinner and more consistent the insulation, the more copper fits into the same winding window — and the stronger, smaller, and more efficient the resulting motor, transformer, or solenoid.\n\nTypes of Enamel Insulation\n\nChoosing the right enamel chemistry is the most important decision when selecting magnet wire. Each insulation type is engineered for a different temperature range, soldering method, and operating environment.\n\nPolyurethane (UEW \/ PUR)\n\nSolderable directly at moderate temperatures without stripping the enamel — the film dissolves into the solder joint. Best for small transformers, relays, timers, clock coils, magnetic heads, and fine-wire electronics where easy termination matters.\n\nTemperature range\n\nTypically 130°C to 180°C thermal class.\n\nPolyester (PEW)\n\nThe most widely used general-purpose enamel, offering a dense, uniform film with good dielectric strength and mechanical toughness at a competitive cost. The workhorse for common motors, appliances, and general winding applications.\n\nTemperature range\n\nTypically 130°C to 155°C thermal class.\n\nPolyester-Imide (EIW)\n\nAn upgraded polyester with superior heat shock resistance, solvent resistance, and refrigerant compatibility. Common in hermetic motors, compressors, automotive alternators, and appliances exposed to high operating temperatures.\n\nTemperature range\n\nTypically 180°C thermal class.\n\nPolyamide-Imide (AIW)\n\nThe premium high-temperature enamel, with exceptional thermal endurance, abrasion resistance, and resistance to overload conditions. Often used as a topcoat over polyester-imide for the highest performance in traction motors, industrial drives, and aerospace windings.\n\nTemperature range\n\nTypically 200°C to 220°C thermal class.\n\nSelf-Bonding (Bondable)\n\nMagnet wire with a thermoplastic or thermosetting overcoat that fuses adjacent turns when heated, producing a self-supporting coil without an impregnating varnish. Ideal for voice coils, speaker coils, sensor coils, and complex free-standing windings.\n\nActivation\n\nHeat, solvent, or resistance heating.\n\nNylon-Overcoated\n\nA thin polyamide top layer added over the base enamel to improve winding lubricity, abrasion resistance, and chemical resistance. Frequently specified for high-speed automatic winding where the wire must survive tight, fast lay-down.\n\nTypical base coats\n\nPolyester or polyester-imide.\n\nMagnet Wire Forms and Shapes\n\nEnameled copper wire is supplied in several conductor geometries to match different winding techniques and slot-fill requirements.\n\nRound Enameled Copper Wire\n\nThe standard form for the majority of motor, transformer, relay, and coil applications. Round magnet wire is available across a very wide AWG range — from fine gauges under 50 AWG for precision electronics to heavy gauges above 10 AWG for large motor and transformer windings.\n\nRectangular and Flat Magnet Wire\n\nRectangular or square enameled copper wire packs more copper into a given slot than round wire, raising the fill factor and improving thermal performance. It is used in high-power traction motors, large generator coils, welding transformers, and high-current inductors where space efficiency is critical.\n\nMulti-Strand and Litz Constructions\n\nFor high-frequency applications, multiple fine enameled wires are twisted or braided together into Litz wire to reduce skin-effect and proximity-effect losses. Stranded magnet wire constructions also offer greater flexibility for bend-intensive coil designs.\n\nTemperature Class and Insulation Build\nUnderstanding Thermal Class\n\nEvery enameled copper wire carries a thermal class that indicates the maximum sustained temperature the insulation can endure over a rated service life — commonly 20,000 hours. Choosing a class with headroom above the actual operating temperature extends motor and transformer life.\n\nThermal Class\tMaximum Sustained Temperature\tTypical Enamel Chemistry\tCommon Applications\n130°C (Class B)\t130°C\tPolyurethane, Polyester\tSmall transformers, relays, general coils\n155°C (Class F)\t155°C\tPolyester, Polyurethane\tAppliance motors, fans, lighting ballasts\n180°C (Class H)\t180°C\tPolyester-Imide\tCompressors, automotive alternators, power tools\n200°C (Class N)\t200°C\tPolyamide-Imide over EIW\tTraction motors, industrial drives\n220°C (Class R)\t220°C\tPolyamide-Imide, aromatic polyimide\tAerospace, high-performance generators\nInsulation Build: Single, Heavy, and Triple\n\n\"Build\" refers to the total thickness of the enamel film. A heavier build increases dielectric withstand voltage but slightly reduces copper fill factor.\n\nSingle build — thinnest insulation; maximum copper density for low-voltage, well-supported windings.\nHeavy build — the most common choice; added dielectric margin for typical motor and transformer voltages.\nTriple build — thickest film; specified for high-voltage or surge-prone windings and for inverter-fed motors exposed to fast voltage pulses.\nHow Magnet Wire Is Made\nCopper Rod Breakdown and Wire Drawing\n\nProduction starts with a copper rod that is pulled through a series of diamond or tungsten-carbide dies, reducing its cross-section in stages until it reaches the target AWG diameter. Fine gauges may go through dozens of drawing steps.\n\nContinuous Annealing\n\nThe drawn wire is passed through a controlled-atmosphere annealing furnace to soften the copper, restore its ductility, and remove work-hardening introduced during drawing. Clean, oxide-free copper is essential for good enamel adhesion.\n\nEnamel Application and Curing\n\nLiquid enamel varnish is applied by felt or die and cured in a long, temperature-controlled oven. The wire makes multiple passes — often 6 to 12 or more — building the film layer by layer to the required build and ensuring complete coverage without pinholes.\n\nLubrication and Spooling\n\nA thin surface lubricant may be applied to help the wire feed smoothly through high-speed winding machines. The finished enameled copper wire is then spooled onto plastic or metal reels in continuous lengths.\n\nIn-Line Quality Control\n\nEvery spool is checked for continuity, insulation defects (pinholes and bare spots via high-voltage spark testing), dimensional consistency, surface finish, and adhesion. Thermal and dielectric properties are verified on sampled production lots.\n\nApplications of Enameled Copper Wire\n\nBecause roughly 90% of all electrical energy passes through a motor, transformer, or coil at some point, magnet wire is one of the most widely used conductors in the modern economy.\n\nElectric Motors and Generators\n\nIndustrial motors, EV traction motors, appliance motors, servo motors, fans, pumps, and portable generators all rely on enameled copper wire in their stator and rotor windings.\n\nTransformers and Inductors\n\nPower transformers, distribution transformers, high-frequency switch-mode transformers, toroidal inductors, chokes, and ballasts use solderable or high-temperature magnet wire depending on frequency and voltage.\n\nAutomotive Electrification\n\nAlternators, starter motors, electric power steering, ABS actuators, on-board chargers, and EV drivetrain components use high-temperature polyester-imide and polyamide-imide magnet wire.\n\nRelays, Solenoids, and Actuators\n\nFine-gauge polyurethane magnet wire is wound into relay coils, solenoid valves, contactors, and linear actuators where direct solderability and compact size matter.\n\nConsumer Electronics and Audio\n\nSpeaker voice coils, headphone drivers, guitar pickups, watch coils, camera actuators, wireless-charging coils, and magnetic sensor coils use self-bonding and fine-gauge enameled wire.\n\nRenewable Energy and Industry\n\nWind turbine generators, solar inverters, welding equipment, induction heaters, UPS systems, and magnet assemblies depend on heavy-build, high-temperature magnet wire for long service life.\n\nTechnical Specifications\nParameter\tRange \/ Options\nProduct name\tMagnet Wire \/ Enameled Copper Wire \/ Winding Wire\nConductor material\tHigh-purity copper (round, rectangular, or stranded)\nAWG range\tFine gauges (50+ AWG) through heavy gauges (4–10 AWG and larger); metric diameters also available\nInsulation chemistry\tPolyurethane (UEW), Polyester (PEW), Polyester-Imide (EIW), Polyamide-Imide (AIW), composite dual coats\nThermal class\t130°C \/ 155°C \/ 180°C \/ 200°C \/ 220°C\nInsulation build\tSingle, heavy, triple\nOvercoat options\tNylon overcoat, self-bonding overcoat, paraffin or nylon lubricant\nConductor shape\tRound, rectangular \/ flat, square, Litz \/ stranded\nSpool packaging\tPlastic spools, metal reels, barrel pack; custom put-ups and continuous lengths\nStandards compliance\tNEMA MW 1000, IEC 60317, JIS C 3202; RoHS and REACH compliant\nSolderability\tDirect-solderable on polyurethane types; other types require mechanical or thermal stripping\nTypical colors\tNatural amber\/clear; red, green, blue, and other colors available for identification\n\nAWG (American Wire Gauge) is the standard sizing system used in North America. If your design uses metric diameters, we can cross-reference and supply to the equivalent AWG size.\n\nValue-Added Processing Services\n\nBeyond supplying raw enameled copper wire on standard spools, RapidKeen provides processing that saves time and waste on your production line.\n\nCut-to-Length and Precision Spooling\n\nWire can be supplied in exact continuous lengths, respooled onto your preferred spool type, or traverse-wound for tangle-free payout on high-speed winding equipment. This reduces setup time and scrap from short ends.\n\nStranding, Twisting, and Bunching\n\nMultiple fine magnet wires can be stranded, twisted, or bunched into Litz or multi-strand constructions to reduce high-frequency AC losses or improve flexibility for dynamic coil applications.\n\nInsulation Stripping and Termination Preparation\n\nFor non-solderable insulations such as polyester-imide and polyamide-imide, we can supply wire with enamel removed from cut ends using mechanical, thermal, or chemical stripping methods, ready for crimping, welding, or soldering.\n\nTransposing and Formed Coils\n\nFor large rectangular magnet wire used in transformers and traction motors, transposing and edge-bending services reduce circulating-current losses and produce coils that drop directly into your assembly.\n\nWhy Source Magnet Wire from RapidKeen\nConsistent Enamel Quality\n\nMulti-pass enameling with in-line spark testing means uniform film thickness, minimal pinholes, and reliable dielectric performance spool after spool — fewer winding stoppages and field failures.\n\nBroad AWG and Insulation Selection\n\nFrom ultra-fine electronics wire to heavy-gauge motor windings, with every major enamel chemistry and build, you can consolidate enameled copper wire purchases across multiple product lines.\n\nApplication-Focused Support\n\nWe help match thermal class, build, and conductor shape to your voltage, temperature, frequency, and winding method — so you don't over-specify or under-insulate.\n\nFlexible Packaging and Processing\n\nCustom put-ups, cut lengths, stranding, and stripping services align deliveries with your production schedule and reduce in-house handling.\n\nMagnet Wire vs. Related Products\n\nBuyers sometimes compare enameled copper wire with other copper wire products. The distinctions matter for correct selection:\n\nProduct\tInsulation\tTypical Use\nMagnet Wire \/ Enameled Copper Wire\tThin polymer enamel film (micrometers)\tCoil winding: motors, transformers, inductors, solenoids\nInsulated copper hook-up wire\tThick PVC, silicone, or PTFE jacket\tPoint-to-point circuit wiring, harnesses\nBare copper wire\tNone\tGrounding, bus bars, craft, jewelry\nTinned copper wire\tNone (tin plating for soldering)\tElectrical connections, bus bars\nLitz wire\tEnamel film on each individual strand\tHigh-frequency coils, wireless charging, induction\nFrequently Asked Questions\nWhat is the difference between magnet wire and regular copper wire?\n\nMagnet wire is copper wire coated with a very thin enamel insulation, allowing it to be wound into tight coils where turns touch without shorting. Regular copper wire is either bare or covered with a thick plastic jacket intended for circuit wiring, not dense coil winding.\n\nIs magnet wire the same as enameled copper wire?\n\nYes. \"Magnet wire\" is the standard North American term, while \"enameled copper wire,\" \"enameled wire,\" and \"winding wire\" describe the same product internationally. All refer to a copper conductor with a cured polymer film insulation.\n\nCan enameled copper wire be soldered directly?\n\nPolyurethane (UEW) magnet wire is directly solderable — the enamel dissolves in molten solder at around 370–400°C without prior stripping. Polyester, polyester-imide, and polyamide-imide insulations must be stripped mechanically, thermally, or chemically before soldering.\n\nWhich temperature class of magnet wire do I need?\n\nSelect a thermal class with a safety margin above your coil's maximum operating temperature. General-purpose motors often use 155°C or 180°C; automotive and compressor windings commonly use 180°C; traction motors and high-reliability industrial drives use 200°C or 220°C.\n\nWhat does AWG mean for magnet wire?\n\nAWG (American Wire Gauge) is the standard sizing system in North America. A higher AWG number means a thinner wire: 30 AWG is a fine electronics wire, while 14 AWG is a heavy motor winding wire. The gauge determines current capacity and DC resistance.\n\nWhat is self-bonding magnet wire used for?\n\nSelf-bonding magnet wire has an additional adhesive overcoat that fuses turns together when heated, creating a rigid, self-supporting coil without varnish impregnation. It is widely used for speaker voice coils, sensor coils, and intricate coil shapes.\n\nWhy is copper used instead of aluminum for magnet wire?\n\nCopper offers higher electrical conductivity, better thermal performance, and easier termination than aluminum. Aluminum magnet wire is sometimes chosen for large, cost-sensitive transformers because it is lighter and cheaper, but it requires a larger cross-section and special joining techniques.\n\nWhat is the difference between single, heavy, and triple build insulation?\n\nBuild refers to enamel thickness. Single build maximizes copper density for low-voltage windings; heavy build is the general-purpose standard; triple build provides extra dielectric withstand for high-voltage or inverter-fed motors exposed to voltage surges.\n\nKeywords: magnet wire, enameled copper wire, enamel coated copper wire, insulated copper wire, winding wire, copper magnet wire, enameled wire, magnetic wire, coil winding wire, AWG magnet wire, solderable magnet wire, high temperature magnet wire, round magnet wire, flat magnet wire, polyurethane magnet wire, polyester enameled wire, polyester-imide magnet wire, polyamide-imide magnet wire, self-bonding magnet wire, motor winding wire, transformer magnet wire.","brand":"RapidKeen","offers":[{"title":"40 AWG (0.08 mm) \/ 155°C \/ Full Spool 2600 m (8530 ft)","offer_id":43597122994235,"sku":null,"price":19.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4473\/6059\/files\/enameled-copper-magnet-wire-motor-stator-coil-winding.webp?v=1787495234"},{"product_id":"magnet-wire-38-awg-enameled-copper-wire","title":"Magnet Wire 38 AWG Enameled Copper Wire for Coil Winding","description":"\u003cstyle\u003e\n.rk-mw{font-family:-apple-system,BlinkMacSystemFont,\"Segoe UI\",Roboto,Helvetica,Arial,sans-serif;color:#222;line-height:1.75;font-size:16px;max-width:1100px;margin:0 auto;padding:0 16px;box-sizing:border-box}\n.rk-mw *{box-sizing:border-box}\n.rk-mw h2{font-size:26px;color:#005969;margin:42px 0 16px;padding-bottom:10px;border-bottom:3px solid #00AAFF;line-height:1.35}\n.rk-mw h3{font-size:20px;color:#005969;margin:28px 0 10px;line-height:1.4}\n.rk-mw h4{font-size:17px;color:#0a7a8c;margin:20px 0 8px}\n.rk-mw h5{font-size:15px;color:#333;margin:16px 0 6px}\n.rk-mw h6{font-size:14px;color:#555;margin:14px 0 6px;text-transform:uppercase;letter-spacing:.5px}\n.rk-mw p{margin:0 0 14px}\n.rk-mw ul,.rk-mw ol{margin:0 0 16px;padding-left:22px}\n.rk-mw li{margin-bottom:6px}\n.rk-mw a{color:#0078a8;text-decoration:none}\n.rk-mw a:hover{text-decoration:underline}\n.rk-mw .rk-lead{font-size:17px;color:#333;background:#f3fafb;border-left:4px solid #00AAFF;padding:16px 20px;border-radius:0 8px 8px 0;margin:0 0 24px}\n.rk-mw .rk-grid{display:grid;grid-template-columns:repeat(3,1fr);gap:18px;margin:18px 0 24px}\n.rk-mw .rk-grid-2{display:grid;grid-template-columns:repeat(2,1fr);gap:18px;margin:18px 0 24px}\n.rk-mw .rk-card{background:#fafdfe;border:1px solid #e1f0f2;border-radius:10px;padding:18px 20px;transition:box-shadow .2s}\n.rk-mw .rk-card:hover{box-shadow:0 4px 16px rgba(0,89,105,.1)}\n.rk-mw .rk-card h3,.rk-mw .rk-card h4{margin-top:0}\n.rk-mw .rk-table-wrap{overflow-x:auto;margin:16px 0 24px;-webkit-overflow-scrolling:touch}\n.rk-mw table{width:100%;border-collapse:collapse;font-size:15px;min-width:560px}\n.rk-mw th{background:#005969;color:#fff;text-align:left;padding:12px 14px;font-weight:600;white-space:nowrap}\n.rk-mw td{padding:11px 14px;border-bottom:1px solid #e6eef0;vertical-align:top}\n.rk-mw tr:nth-child(even) td{background:#f6fbfc}\n.rk-mw .rk-note{background:#fff8e6;border-left:4px solid #f5b301;padding:14px 18px;border-radius:0 8px 8px 0;margin:16px 0;font-size:15px}\n.rk-mw .rk-kw{font-weight:600;color:#005969}\n.rk-mw .rk-process{counter-reset:step;list-style:none;padding-left:0}\n.rk-mw .rk-process li{position:relative;padding:0 0 18px 48px;border-left:2px solid #b3e5fc;margin-left:16px}\n.rk-mw .rk-process li::before{counter-increment:step;content:counter(step);position:absolute;left:-17px;top:0;width:32px;height:32px;background:#00AAFF;color:#fff;border-radius:50%;display:flex;align-items:center;justify-content:center;font-weight:700;font-size:15px}\n.rk-mw .rk-process li:last-child{border-left:2px solid transparent;padding-bottom:0}\n.rk-mw .rk-process h4{margin:4px 0 6px}\n.rk-mw .rk-faq{border:1px solid #e1f0f2;border-radius:10px;margin-bottom:12px;overflow:hidden}\n.rk-mw .rk-faq h3{margin:0;padding:16px 20px;background:#f3fafb;font-size:17px}\n.rk-mw .rk-faq h3::before{content:\"Q \";color:#00AAFF;font-weight:700}\n.rk-mw .rk-faq .rk-a{padding:0 20px 16px}\n@media(max-width:900px){.rk-mw .rk-grid{grid-template-columns:repeat(2,1fr)}}\n@media(max-width:640px){\n  .rk-mw{font-size:15px;padding:0 12px}\n  .rk-mw h2{font-size:22px;margin:32px 0 12px}\n  .rk-mw h3{font-size:18px}\n  .rk-mw .rk-grid,.rk-mw .rk-grid-2{grid-template-columns:1fr;gap:14px}\n  .rk-mw .rk-lead{font-size:15px;padding:14px 16px}\n  .rk-mw table{font-size:14px}\n  .rk-mw th,.rk-mw td{padding:9px 10px}\n}\n\u003c\/style\u003e\n\u003cdiv class=\"rk-mw\"\u003e\n\u003cp class=\"rk-lead\"\u003e\u003cspan class=\"rk-kw\"\u003eMagnet wire\u003c\/span\u003e — also known as \u003cspan class=\"rk-kw\"\u003eenameled copper wire\u003c\/span\u003e, winding wire, or enamel-coated copper wire — is a copper conductor covered by a thin, tough polymer film that lets thousands of turns sit side by side in a coil without short-circuiting.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

This eliminates the need for separate enamel removal steps such as scraping, chemical stripping, or thermal burn-off, making solderable enameled wire a preferred choice for high-volume coil production where termination speed and consistency are critical.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Our direct-solderable enameled copper wire is built on a high-purity oxygen-free copper core that delivers consistently low electrical resistance and high current-carrying capacity. The polyurethane enamel insulation is applied through a multi-pass enameling process, forming a uniform, concentric, pinhole-free coating that solders cleanly at controlled temperatures while still providing dependable dielectric protection between adjacent coil turns.\n        \u003c\/p\u003e\n        \u003cp class=\"rk-mw-text\"\u003e\n            Every spool of this magnet wire is optimized for automated high-speed coil winding. The surface is engineered for low friction and smooth layer crossover, while the annealed copper core provides balanced elongation and flexibility.

brass, a copper-and-zinc material. It is produced by extrusion and cold drawing into long, straight bars with a constant round cross-section, and it is the most widely used starting stock for turned and machined brass components. In everyday trade language it is also called brass rod, brass round rod, solid brass rod or round brass bar stock.\u003c\/p\u003e\n\u003cp\u003eSmaller diameters are commonly referred to as brass rod and larger diameters as brass round bar, but both describe the same solid round material. Brass round bar balances strength, natural corrosion resistance, an attractive golden finish and outstanding machinability, which is why it is chosen for everything from precision fasteners to visible architectural and decorative parts.\u003c\/p\u003e\n\u003ch4\u003eKey Characteristics of Brass Round Bar\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior machinability:\u003c\/strong\u003e Brass round rod cuts, drills, taps and turns with light tool pressure and clean, short chips, ideal for high-volume CNC and lathe work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural corrosion resistance:\u003c\/strong\u003e The copper content gives brass round bar built-in resistance to atmospheric and moisture corrosion, so it does not rust like steel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBendable and formable:\u003c\/strong\u003e In softer tempers the brass rod can be bent, headed and formed without cracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttractive golden finish:\u003c\/strong\u003e Polished or brushed brass round bar delivers a premium look for visible components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGood conductivity:\u003c\/strong\u003e Solid brass rod carries useful electrical and thermal conductivity for connectors, pins and heat-transfer parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNaturally hygienic surface:\u003c\/strong\u003e As a copper-based material, brass round bar naturally limits bacterial growth on frequently touched surfaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section rk-section-alt\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eWhy Choose Brass Round Bar?\u003c\/h2\u003e\n\u003cp class=\"rk-lead-center\"\u003eBrass round bar combines the reliability of copper with the strength and economy of zinc, giving machinists and fabricators a round stock that performs in both function and finish.\u003c\/p\u003e\n\u003cdiv class=\"rk-feature-grid\"\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e⚙\u003c\/div\u003e\n\u003ch4\u003eMachinability\u003c\/h4\u003e\n\u003cp\u003eBrass round rod turns faster and cleaner than most metals, cutting cycle times and tool wear on the lathe.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🛡\u003c\/div\u003e\n\u003ch4\u003eCorrosion Resistant\u003c\/h4\u003e\n\u003cp\u003eNaturally resistant to rust and moisture, brass round bar performs reliably indoors and outdoors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e✨\u003c\/div\u003e\n\u003ch4\u003eAesthetic Finish\u003c\/h4\u003e\n\u003cp\u003eThe warm golden lustre of polished brass rod elevates hardware, lighting and decorative pieces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e💰\u003c\/div\u003e\n\u003ch4\u003eCost Effective\u003c\/h4\u003e\n\u003cp\u003eRound brass bar stock delivers dependable performance at a competitive material cost.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔌\u003c\/div\u003e\n\u003ch4\u003eConductivity\u003c\/h4\u003e\n\u003cp\u003eSolid brass round bar offers reliable electrical and thermal conductivity for pins and connectors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🧪\u003c\/div\u003e\n\u003ch4\u003eHygienic Surface\u003c\/h4\u003e\n\u003cp\u003eCopper-based brass rod surfaces naturally reduce microbial build-up on touch parts.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔧\u003c\/div\u003e\n\u003ch4\u003eFormability\u003c\/h4\u003e\n\u003cp\u003eBrass round bar can be bent, headed and formed into shapes without losing strength in the right temper.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e♻\u003c\/div\u003e\n\u003ch4\u003eRecyclable\u003c\/h4\u003e\n\u003cp\u003eBrass round rod is fully recyclable without loss of properties, supporting cleaner production.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eBrass Round Bar Sizes, Tempers \u0026amp;

seamless copper pipe, or hollow copper tube — is a hollow, seamless copper tube drawn from 99.9% pure copper 110, with no welded seam along its length. Small copper tubing is chosen for cooling coils, refrigerant and fluid lines, gas and oil delivery, instrumentation and laboratory systems, heat exchangers, manifold and nozzle components, and DIY bending and flaring projects. The seamless wall bends, flares, brazes, and solders cleanly, and the inner bore is smooth and continuous for dependable flow.\u003c\/p\u003e\n\u003cp\u003eThis small-diameter range is selected by its \u003cstrong\u003eouter diameter (OD)\u003c\/strong\u003e with a fixed standard wall, supplied in straight lengths or cut to the exact length your assembly requires, across the United States.

class=\"rk-lead\"\u003e\u003cspan class=\"rk-kw\"\u003eMagnet wire\u003c\/span\u003e — also known as \u003cspan class=\"rk-kw\"\u003eenameled copper wire\u003c\/span\u003e, winding wire, or enamel-coated copper wire — is a copper conductor covered by a thin, tough polymer film that lets thousands of turns sit side by side in a coil without short-circuiting. It is the fundamental conductor inside every motor, transformer, inductor, and electromagnetic device that converts electricity into motion, voltage, or magnetic force.\u003c\/p\u003e\n\u003ch2\u003eWhat Is Magnet Wire?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMagnet wire\u003c\/strong\u003e is an insulated electrical conductor, almost always copper (and sometimes aluminum), designed to be wound into tight coils. The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called \u003cstrong\u003eenameled wire\u003c\/strong\u003e or \u003cstrong\u003ewinding wire\u003c\/strong\u003e. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\u003c\/p\u003e\n\u003cp\u003eThe key difference between \u003cstrong\u003eenameled copper wire\u003c\/strong\u003e and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\u003c\/p\u003e\n\u003ch3\u003eThe Conductor: High-Purity Copper\u003c\/h3\u003e\n\u003cp\u003eThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\u003c\/p\u003e\n\u003ch3\u003eThe Insulation: Enamel Polymer Film\u003c\/h3\u003e\n\u003cp\u003eThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\u003c\/p\u003e\n\u003ch3\u003eHow Enameled Copper Wire Works in a Coil\u003c\/h3\u003e\n\u003cp\u003eWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns. The thinner and more consistent the insulation, the more copper fits into the same winding window — and the stronger, smaller, and more efficient the resulting motor, transformer, or solenoid.\u003c\/p\u003e\n\u003ch2\u003eTypes of Enamel Insulation\u003c\/h2\u003e\n\u003cp\u003eChoosing the right enamel chemistry is the most important decision when selecting magnet wire. Each insulation type is engineered for a different temperature range, soldering method, and operating environment.\u003c\/p\u003e\n\u003cdiv class=\"rk-grid\"\u003e\n\u003cdiv class=\"rk-card\"\u003e\n\u003ch3\u003ePolyurethane (UEW \/ PUR)\u003c\/h3\u003e\n\u003cp\u003eSolderable directly at moderate temperatures without stripping the enamel — the film dissolves into the solder joint.

It is the fundamental conductor inside every motor, transformer, inductor, and electromagnetic device that converts electricity into motion, voltage, or magnetic force.\n\nWhat Is Magnet Wire?\n\nMagnet wire is an insulated electrical conductor, almost always copper (and sometimes aluminum), designed to be wound into tight coils. The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called enameled wire or winding wire. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\n\nThe key difference between enameled copper wire and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\n\nThe Conductor: High-Purity Copper\n\nThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\n\nThe Insulation: Enamel Polymer Film\n\nThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\n\nHow Enameled Copper Wire Works in a Coil\n\nWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns. The thinner and more consistent the insulation, the more copper fits into the same winding window — and the stronger, smaller, and more efficient the resulting motor, transformer, or solenoid.\n\nTypes of Enamel Insulation\n\nChoosing the right enamel chemistry is the most important decision when selecting magnet wire. Each insulation type is engineered for a different temperature range, soldering method, and operating environment.\n\nPolyurethane (UEW \/ PUR)\n\nSolderable directly at moderate temperatures without stripping the enamel — the film dissolves into the solder joint. Best for small transformers, relays, timers, clock coils, magnetic heads, and fine-wire electronics where easy termination matters.\n\nTemperature range\n\nTypically 130°C to 180°C thermal class.\n\nPolyester (PEW)\n\nThe most widely used general-purpose enamel, offering a dense, uniform film with good dielectric strength and mechanical toughness at a competitive cost. The workhorse for common motors, appliances, and general winding applications.\n\nTemperature range\n\nTypically 130°C to 155°C thermal class.\n\nPolyester-Imide (EIW)\n\nAn upgraded polyester with superior heat shock resistance, solvent resistance, and refrigerant compatibility. Common in hermetic motors, compressors, automotive alternators, and appliances exposed to high operating temperatures.\n\nTemperature range\n\nTypically 180°C thermal class.\n\nPolyamide-Imide (AIW)\n\nThe premium high-temperature enamel, with exceptional thermal endurance, abrasion resistance, and resistance to overload conditions. Often used as a topcoat over polyester-imide for the highest performance in traction motors, industrial drives, and aerospace windings.\n\nTemperature range\n\nTypically 200°C to 220°C thermal class.\n\nSelf-Bonding (Bondable)\n\nMagnet wire with a thermoplastic or thermosetting overcoat that fuses adjacent turns when heated, producing a self-supporting coil without an impregnating varnish. Ideal for voice coils, speaker coils, sensor coils, and complex free-standing windings.\n\nActivation\n\nHeat, solvent, or resistance heating.\n\nNylon-Overcoated\n\nA thin polyamide top layer added over the base enamel to improve winding lubricity, abrasion resistance, and chemical resistance. Frequently specified for high-speed automatic winding where the wire must survive tight, fast lay-down.\n\nTypical base coats\n\nPolyester or polyester-imide.\n\nMagnet Wire Forms and Shapes\n\nEnameled copper wire is supplied in several conductor geometries to match different winding techniques and slot-fill requirements.\n\nRound Enameled Copper Wire\n\nThe standard form for the majority of motor, transformer, relay, and coil applications. Round magnet wire is available across a very wide AWG range — from fine gauges under 50 AWG for precision electronics to heavy gauges above 10 AWG for large motor and transformer windings.\n\nRectangular and Flat Magnet Wire\n\nRectangular or square enameled copper wire packs more copper into a given slot than round wire, raising the fill factor and improving thermal performance. It is used in high-power traction motors, large generator coils, welding transformers, and high-current inductors where space efficiency is critical.\n\nMulti-Strand and Litz Constructions\n\nFor high-frequency applications, multiple fine enameled wires are twisted or braided together into Litz wire to reduce skin-effect and proximity-effect losses. Stranded magnet wire constructions also offer greater flexibility for bend-intensive coil designs.\n\nTemperature Class and Insulation Build\nUnderstanding Thermal Class\n\nEvery enameled copper wire carries a thermal class that indicates the maximum sustained temperature the insulation can endure over a rated service life — commonly 20,000 hours. Choosing a class with headroom above the actual operating temperature extends motor and transformer life.\n\nThermal Class\tMaximum Sustained Temperature\tTypical Enamel Chemistry\tCommon Applications\n130°C (Class B)\t130°C\tPolyurethane, Polyester\tSmall transformers, relays, general coils\n155°C (Class F)\t155°C\tPolyester, Polyurethane\tAppliance motors, fans, lighting ballasts\n180°C (Class H)\t180°C\tPolyester-Imide\tCompressors, automotive alternators, power tools\n200°C (Class N)\t200°C\tPolyamide-Imide over EIW\tTraction motors, industrial drives\n220°C (Class R)\t220°C\tPolyamide-Imide, aromatic polyimide\tAerospace, high-performance generators\nInsulation Build: Single, Heavy, and Triple\n\n\"Build\" refers to the total thickness of the enamel film. A heavier build increases dielectric withstand voltage but slightly reduces copper fill factor.\n\nSingle build — thinnest insulation; maximum copper density for low-voltage, well-supported windings.\nHeavy build — the most common choice; added dielectric margin for typical motor and transformer voltages.\nTriple build — thickest film; specified for high-voltage or surge-prone windings and for inverter-fed motors exposed to fast voltage pulses.\nHow Magnet Wire Is Made\nCopper Rod Breakdown and Wire Drawing\n\nProduction starts with a copper rod that is pulled through a series of diamond or tungsten-carbide dies, reducing its cross-section in stages until it reaches the target AWG diameter. Fine gauges may go through dozens of drawing steps.\n\nContinuous Annealing\n\nThe drawn wire is passed through a controlled-atmosphere annealing furnace to soften the copper, restore its ductility, and remove work-hardening introduced during drawing. Clean, oxide-free copper is essential for good enamel adhesion.\n\nEnamel Application and Curing\n\nLiquid enamel varnish is applied by felt or die and cured in a long, temperature-controlled oven. The wire makes multiple passes — often 6 to 12 or more — building the film layer by layer to the required build and ensuring complete coverage without pinholes.\n\nLubrication and Spooling\n\nA thin surface lubricant may be applied to help the wire feed smoothly through high-speed winding machines. The finished enameled copper wire is then spooled onto plastic or metal reels in continuous lengths.\n\nIn-Line Quality Control\n\nEvery spool is checked for continuity, insulation defects (pinholes and bare spots via high-voltage spark testing), dimensional consistency, surface finish, and adhesion. Thermal and dielectric properties are verified on sampled production lots.\n\nApplications of Enameled Copper Wire\n\nBecause roughly 90% of all electrical energy passes through a motor, transformer, or coil at some point, magnet wire is one of the most widely used conductors in the modern economy.\n\nElectric Motors and Generators\n\nIndustrial motors, EV traction motors, appliance motors, servo motors, fans, pumps, and portable generators all rely on enameled copper wire in their stator and rotor windings.\n\nTransformers and Inductors\n\nPower transformers, distribution transformers, high-frequency switch-mode transformers, toroidal inductors, chokes, and ballasts use solderable or high-temperature magnet wire depending on frequency and voltage.\n\nAutomotive Electrification\n\nAlternators, starter motors, electric power steering, ABS actuators, on-board chargers, and EV drivetrain components use high-temperature polyester-imide and polyamide-imide magnet wire.\n\nRelays, Solenoids, and Actuators\n\nFine-gauge polyurethane magnet wire is wound into relay coils, solenoid valves, contactors, and linear actuators where direct solderability and compact size matter.\n\nConsumer Electronics and Audio\n\nSpeaker voice coils, headphone drivers, guitar pickups, watch coils, camera actuators, wireless-charging coils, and magnetic sensor coils use self-bonding and fine-gauge enameled wire.\n\nRenewable Energy and Industry\n\nWind turbine generators, solar inverters, welding equipment, induction heaters, UPS systems, and magnet assemblies depend on heavy-build, high-temperature magnet wire for long service life.\n\nTechnical Specifications\nParameter\tRange \/ Options\nProduct name\tMagnet Wire \/ Enameled Copper Wire \/ Winding Wire\nConductor material\tHigh-purity copper (round, rectangular, or stranded)\nAWG range\tFine gauges (50+ AWG) through heavy gauges (4–10 AWG and larger); metric diameters also available\nInsulation chemistry\tPolyurethane (UEW), Polyester (PEW), Polyester-Imide (EIW), Polyamide-Imide (AIW), composite dual coats\nThermal class\t130°C \/ 155°C \/ 180°C \/ 200°C \/ 220°C\nInsulation build\tSingle, heavy, triple\nOvercoat options\tNylon overcoat, self-bonding overcoat, paraffin or nylon lubricant\nConductor shape\tRound, rectangular \/ flat, square, Litz \/ stranded\nSpool packaging\tPlastic spools, metal reels, barrel pack; custom put-ups and continuous lengths\nStandards compliance\tNEMA MW 1000, IEC 60317, JIS C 3202; RoHS and REACH compliant\nSolderability\tDirect-solderable on polyurethane types; other types require mechanical or thermal stripping\nTypical colors\tNatural amber\/clear; red, green, blue, and other colors available for identification\n\nAWG (American Wire Gauge) is the standard sizing system used in North America.

Regular copper wire is either bare or covered with a thick plastic jacket intended for circuit wiring, not dense coil winding.\n\nIs magnet wire the same as enameled copper wire?\n\nYes. \"Magnet wire\" is the standard North American term, while \"enameled copper wire,\" \"enameled wire,\" and \"winding wire\" describe the same product internationally. All refer to a copper conductor with a cured polymer film insulation.\n\nCan enameled copper wire be soldered directly?\n\nPolyurethane (UEW) magnet wire is directly solderable — the enamel dissolves in molten solder at around 370–400°C without prior stripping. Polyester, polyester-imide, and polyamide-imide insulations must be stripped mechanically, thermally, or chemically before soldering.\n\nWhich temperature class of magnet wire do I need?\n\nSelect a thermal class with a safety margin above your coil's maximum operating temperature. General-purpose motors often use 155°C or 180°C; automotive and compressor windings commonly use 180°C; traction motors and high-reliability industrial drives use 200°C or 220°C.\n\nWhat does AWG mean for magnet wire?\n\nAWG (American Wire Gauge) is the standard sizing system in North America. A higher AWG number means a thinner wire: 30 AWG is a fine electronics wire, while 14 AWG is a heavy motor winding wire. The gauge determines current capacity and DC resistance.\n\nWhat is self-bonding magnet wire used for?\n\nSelf-bonding magnet wire has an additional adhesive overcoat that fuses turns together when heated, creating a rigid, self-supporting coil without varnish impregnation. It is widely used for speaker voice coils, sensor coils, and intricate coil shapes.\n\nWhy is copper used instead of aluminum for magnet wire?\n\nCopper offers higher electrical conductivity, better thermal performance, and easier termination than aluminum. Aluminum magnet wire is sometimes chosen for large, cost-sensitive transformers because it is lighter and cheaper, but it requires a larger cross-section and special joining techniques.\n\nWhat is the difference between single, heavy, and triple build insulation?\n\nBuild refers to enamel thickness. Single build maximizes copper density for low-voltage windings; heavy build is the general-purpose standard; triple build provides extra dielectric withstand for high-voltage or inverter-fed motors exposed to voltage surges.\n\nKeywords: magnet wire, enameled copper wire, enamel coated copper wire, insulated copper wire, winding wire, copper magnet wire, enameled wire, magnetic wire, coil winding wire, AWG magnet wire, solderable magnet wire, high temperature magnet wire, round magnet wire, flat magnet wire, polyurethane magnet wire, polyester enameled wire, polyester-imide magnet wire, polyamide-imide magnet wire, self-bonding magnet wire, motor winding wire, transformer magnet wire.","brand":"RapidKeen","offers":[{"title":"39 AWG (0.09 mm) \/ 155°C \/ Full Spool 2000 m (6562ft)","offer_id":44049281744955,"sku":null,"price":19.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4473\/6059\/files\/enameled-copper-magnet-wire-motor-stator-coil-winding.webp?v=1787495234"},{"product_id":"magnet-wire-36-awg-enameled-copper-wire-for-coil-winding","title":"Magnet Wire 36 AWG 0.12mm Enameled Copper Wire for Coil Winding","description":"\u003cstyle\u003e\n.rk-mw{font-family:-apple-system,BlinkMacSystemFont,\"Segoe UI\",Roboto,Helvetica,Arial,sans-serif;color:#222;line-height:1.75;font-size:16px;max-width:1100px;margin:0 auto;padding:0 16px;box-sizing:border-box}\n.rk-mw *{box-sizing:border-box}\n.rk-mw h2{font-size:26px;color:#005969;margin:42px 0 16px;padding-bottom:10px;border-bottom:3px solid #00AAFF;line-height:1.35}\n.rk-mw h3{font-size:20px;color:#005969;margin:28px 0 10px;line-height:1.4}\n.rk-mw h4{font-size:17px;color:#0a7a8c;margin:20px 0 8px}\n.rk-mw h5{font-size:15px;color:#333;margin:16px 0 6px}\n.rk-mw h6{font-size:14px;color:#555;margin:14px 0 6px;text-transform:uppercase;letter-spacing:.5px}\n.rk-mw p{margin:0 0 14px}\n.rk-mw ul,.rk-mw ol{margin:0 0 16px;padding-left:22px}\n.rk-mw li{margin-bottom:6px}\n.rk-mw a{color:#0078a8;text-decoration:none}\n.rk-mw a:hover{text-decoration:underline}\n.rk-mw .rk-lead{font-size:17px;color:#333;background:#f3fafb;border-left:4px solid #00AAFF;padding:16px 20px;border-radius:0 8px 8px 0;margin:0 0 24px}\n.rk-mw .rk-grid{display:grid;grid-template-columns:repeat(3,1fr);gap:18px;margin:18px 0 24px}\n.rk-mw .rk-grid-2{display:grid;grid-template-columns:repeat(2,1fr);gap:18px;margin:18px 0 24px}\n.rk-mw .rk-card{background:#fafdfe;border:1px solid #e1f0f2;border-radius:10px;padding:18px 20px;transition:box-shadow .2s}\n.rk-mw .rk-card:hover{box-shadow:0 4px 16px rgba(0,89,105,.1)}\n.rk-mw .rk-card h3,.rk-mw .rk-card h4{margin-top:0}\n.rk-mw .rk-table-wrap{overflow-x:auto;margin:16px 0 24px;-webkit-overflow-scrolling:touch}\n.rk-mw table{width:100%;border-collapse:collapse;font-size:15px;min-width:560px}\n.rk-mw th{background:#005969;color:#fff;text-align:left;padding:12px 14px;font-weight:600;white-space:nowrap}\n.rk-mw td{padding:11px 14px;border-bottom:1px solid #e6eef0;vertical-align:top}\n.rk-mw tr:nth-child(even) td{background:#f6fbfc}\n.rk-mw .rk-note{background:#fff8e6;border-left:4px solid #f5b301;padding:14px 18px;border-radius:0 8px 8px 0;margin:16px 0;font-size:15px}\n.rk-mw .rk-kw{font-weight:600;color:#005969}\n.rk-mw .rk-process{counter-reset:step;list-style:none;padding-left:0}\n.rk-mw .rk-process li{position:relative;padding:0 0 18px 48px;border-left:2px solid #b3e5fc;margin-left:16px}\n.rk-mw .rk-process li::before{counter-increment:step;content:counter(step);position:absolute;left:-17px;top:0;width:32px;height:32px;background:#00AAFF;color:#fff;border-radius:50%;display:flex;align-items:center;justify-content:center;font-weight:700;font-size:15px}\n.rk-mw .rk-process li:last-child{border-left:2px solid transparent;padding-bottom:0}\n.rk-mw .rk-process h4{margin:4px 0 6px}\n.rk-mw .rk-faq{border:1px solid #e1f0f2;border-radius:10px;margin-bottom:12px;overflow:hidden}\n.rk-mw .rk-faq h3{margin:0;padding:16px 20px;background:#f3fafb;font-size:17px}\n.rk-mw .rk-faq h3::before{content:\"Q \";color:#00AAFF;font-weight:700}\n.rk-mw .rk-faq .rk-a{padding:0 20px 16px}\n@media(max-width:900px){.rk-mw .rk-grid{grid-template-columns:repeat(2,1fr)}}\n@media(max-width:640px){\n  .rk-mw{font-size:15px;padding:0 12px}\n  .rk-mw h2{font-size:22px;margin:32px 0 12px}\n  .rk-mw h3{font-size:18px}\n  .rk-mw .rk-grid,.rk-mw .rk-grid-2{grid-template-columns:1fr;gap:14px}\n  .rk-mw .rk-lead{font-size:15px;padding:14px 16px}\n  .rk-mw table{font-size:14px}\n  .rk-mw th,.rk-mw td{padding:9px 10px}\n}\n\u003c\/style\u003e\n\u003cdiv class=\"rk-mw\"\u003e\n\u003cp class=\"rk-lead\"\u003e\u003cspan class=\"rk-kw\"\u003eMagnet wire\u003c\/span\u003e — also known as \u003cspan class=\"rk-kw\"\u003eenameled copper wire\u003c\/span\u003e, winding wire, or enamel-coated copper wire — is a copper conductor covered by a thin, tough polymer film that lets thousands of turns sit side by side in a coil without short-circuiting.

The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called \u003cstrong\u003eenameled wire\u003c\/strong\u003e or \u003cstrong\u003ewinding wire\u003c\/strong\u003e. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\u003c\/p\u003e\n\u003cp\u003eThe key difference between \u003cstrong\u003eenameled copper wire\u003c\/strong\u003e and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\u003c\/p\u003e\n\u003ch3\u003eThe Conductor: High-Purity Copper\u003c\/h3\u003e\n\u003cp\u003eThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\u003c\/p\u003e\n\u003ch3\u003eThe Insulation: Enamel Polymer Film\u003c\/h3\u003e\n\u003cp\u003eThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\u003c\/p\u003e\n\u003ch3\u003eHow Enameled Copper Wire Works in a Coil\u003c\/h3\u003e\n\u003cp\u003eWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns.

The term \"magnet wire\" is the standard industry name in North America and is defined by the NEMA MW 1000 standard; internationally the same product is called \u003cstrong\u003eenameled wire\u003c\/strong\u003e or \u003cstrong\u003ewinding wire\u003c\/strong\u003e. Despite the word \"enamel,\" the insulation is not glassy porcelain or paint — it is one or more layers of high-performance polymer film applied and cured in precise passes.\u003c\/p\u003e\n\u003cp\u003eThe key difference between \u003cstrong\u003eenameled copper wire\u003c\/strong\u003e and ordinary insulated copper wire is insulation thickness. A typical plastic-jacketed wire adds a millimeter or more of insulation, while magnet wire's enamel film is only a few micrometers thick. That is what allows compact, high-density coil windings where the copper fill factor — the share of cross-section actually occupied by copper — is as high as possible.\u003c\/p\u003e\n\u003ch3\u003eThe Conductor: High-Purity Copper\u003c\/h3\u003e\n\u003cp\u003eThe conductor is electrolytically refined or oxygen-free copper, selected for its superior electrical conductivity, thermal conductivity, and ductility. Copper's low resistance cuts energy loss and heat rise, and after annealing it becomes soft enough to draw down to very fine gauges and wind around sharp bends without work-hardening or breaking.\u003c\/p\u003e\n\u003ch3\u003eThe Insulation: Enamel Polymer Film\u003c\/h3\u003e\n\u003cp\u003eThe enamel coating is applied as a liquid varnish and cured at high temperature, building up a uniform, flexible, dielectric film in multiple passes. Depending on the chemistry, the insulation provides a specific balance of thermal endurance, dielectric strength, solderability, abrasion resistance, and resistance to solvents and refrigerants. Some constructions add a nylon overcoat or a self-bonding top layer for heat-activated adhesion.\u003c\/p\u003e\n\u003ch3\u003eHow Enameled Copper Wire Works in a Coil\u003c\/h3\u003e\n\u003cp\u003eWhen current flows through a coil of magnet wire, every turn contributes to a concentrated electromagnetic field. The enamel film forces current to follow the long helical path of the conductor instead of jumping between touching turns. The thinner and more consistent the insulation, the more copper fits into the same winding window — and the stronger, smaller, and more efficient the resulting motor, transformer, or solenoid.\u003c\/p\u003e\n\u003ch2\u003eTypes of Enamel Insulation\u003c\/h2\u003e\n\u003cp\u003eChoosing the right enamel chemistry is the most important decision when selecting magnet wire.

flat face that is noticeably wider than it is thick. It is produced by extrusion or drawing and is one of the most versatile brass profiles for fabrication. In trade language it is also called brass rectangular bar, brass rectangle bar, brass flat, brass flats, brass flat stock or rectangular brass rod.\u003c\/p\u003e\n\u003cp\u003eMetal Supermarkets defines flat bar and rectangular bar as the same product, measured first by width and then by thickness. Unlike thin brass strip, which can be coiled, brass flat bar is a thicker, rigid, straight section chosen whenever a part needs stiffness, a flat mounting face or clean machined edges. It machines, drills, punches, bends, brazes and polishes reliably, with the warm golden look brass is known for.\u003c\/p\u003e\n\u003ch4\u003eKey Characteristics of Brass Flat Bar\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide flat face:\u003c\/strong\u003e the rectangular section gives a stable surface for mounting, bonding, laminating and surface-mounted hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGood machinability:\u003c\/strong\u003e brass flat stock mills, drills, punches and taps cleanly with low tool wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBendable and formable:\u003c\/strong\u003e in softer tempers the flat brass bar bends into brackets, frames and curved trim.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural corrosion resistance:\u003c\/strong\u003e copper-based brass flat bar does not rust in normal atmosphere and holds up outdoors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttractive finish:\u003c\/strong\u003e brushed or polished rectangular brass bar delivers a premium decorative surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUseful conductivity:\u003c\/strong\u003e solid brass flat stock serves as compact bus bars, connectors and grounding strips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section rk-section-alt\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eWhy Choose Brass Flat Bar?\u003c\/h2\u003e\n\u003cp class=\"rk-lead-center\"\u003eRectangular brass flat bar combines a rigid flat section with easy fabrication and a classic brass finish, making it equally useful for structural and visible parts.\u003c\/p\u003e\n\u003cdiv class=\"rk-feature-grid\"\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e⚙\u003c\/div\u003e\n\u003ch4\u003eEasy to Machine\u003c\/h4\u003e\n\u003cp\u003eBrass flat stock mills, drills and punches cleanly for brackets, plates and precision hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🛡\u003c\/div\u003e\n\u003ch4\u003eCorrosion Resistant\u003c\/h4\u003e\n\u003cp\u003eFlat brass bar resists rust and moisture indoors and in sheltered outdoor use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e✨\u003c\/div\u003e\n\u003ch4\u003eDecorative Face\u003c\/h4\u003e\n\u003cp\u003eThe broad face polishes or brushes beautifully for trim, inlay and furniture metalwork.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e📎\u003c\/div\u003e\n\u003ch4\u003eStable \u0026amp;

straight metal bar with a square cross-section — four equal flat faces meeting at right angles. It is produced by extrusion or drawing and is valued for its symmetry, flat mounting faces and clean machinability. In trade language it is also called brass square rod, square brass bar, brass square stock or solid brass square bar.\u003c\/p\u003e\n\u003cp\u003eA square section is measured across flats (the distance between two opposite flat faces), which distinguishes it from round bar (measured by diameter), flat bar (measured width × thickness) and hex bar (six-sided across flats). Brass square bar machines, mills, turns, drills, files and polishes reliably, with the warm golden finish that makes brass equally suitable for working parts and visible metalwork. Short cut lengths are ordered as brass square block.\u003c\/p\u003e\n\u003ch4\u003eKey Characteristics of Brass Square Bar\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour equal flat faces:\u003c\/strong\u003e the symmetrical square section mounts, seats and aligns cleanly in fixtures and frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGood machinability:\u003c\/strong\u003e brass square stock mills, turns and drills smoothly with low tool wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRigid and straight:\u003c\/strong\u003e solid square bar resists twist and holds a true line for rails and structural trim.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural corrosion resistance:\u003c\/strong\u003e copper-based brass square bar does not rust in normal atmosphere.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttractive finish:\u003c\/strong\u003e polished or brushed square brass bar gives crisp edges and a premium look.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormable in soft temper:\u003c\/strong\u003e softer square rod can be bent, headed and fabricated without cracking.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section rk-section-alt\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eWhy Choose Brass Square Bar?\u003c\/h2\u003e\n\u003cp class=\"rk-lead-center\"\u003eBrass square bar combines a rigid, symmetrical section with easy machining and a classic brass finish for both functional and decorative parts.\u003c\/p\u003e\n\u003cdiv class=\"rk-feature-grid\"\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e⚙\u003c\/div\u003e\n\u003ch4\u003eEasy to Machine\u003c\/h4\u003e\n\u003cp\u003eBrass square stock mills, turns and drills cleanly into precise square parts.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e📎\u003c\/div\u003e\n\u003ch4\u003eFlat Stable Faces\u003c\/h4\u003e\n\u003cp\u003eFour equal faces seat and mount squarely without rolling or twisting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🛡\u003c\/div\u003e\n\u003ch4\u003eCorrosion Resistant\u003c\/h4\u003e\n\u003cp\u003eSquare brass bar resists rust and moisture indoors and outdoors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e✨\u003c\/div\u003e\n\u003ch4\u003eCrisp Decorative Look\u003c\/h4\u003e\n\u003cp\u003eSharp, even edges polish beautifully for trim, grilles and metalwork.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔧\u003c\/div\u003e\n\u003ch4\u003eRigid \u0026amp;

straight metal bar with a regular hexagonal cross-section — six equal flat faces running its full length. It is produced by extrusion or drawing and is also called brass hex rod, hexagonal brass bar, hex brass bar, six-sided brass bar or brass hex stock. It is measured across flats, the distance between two opposite flat faces.\u003c\/p\u003e\n\u003cp\u003eThe hexagonal shape is deliberate: the flat faces give a wrench or spanner a positive, non-slip grip and stop the part from rotating in a fitting or chuck. This is why brass hex bar is the standard starting material for turned fasteners, nuts, bolts, valve stems and connector bodies. It turns, drills, taps and threads exceptionally cleanly on CNC and automatic lathes, with the warm golden finish and natural corrosion resistance brass is known for.\u003c\/p\u003e\n\u003ch4\u003eKey Characteristics of Brass Hex Bar\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix flat grip faces:\u003c\/strong\u003e the hexagonal section gives a secure wrench grip and prevents rotation in fittings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent turning:\u003c\/strong\u003e brass hex rod machines fast and cleanly on automatic and CNC lathes for high-volume parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasured across flats:\u003c\/strong\u003e hex bar is specified by its across-flats dimension in millimetres or inches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural corrosion resistance:\u003c\/strong\u003e copper-based brass hex stock does not rust in normal atmosphere.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttractive finish:\u003c\/strong\u003e the flat faces polish to a clean, premium golden surface for visible hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGood conductivity:\u003c\/strong\u003e hexagonal brass bar serves for terminals, connectors and electrical fittings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section rk-section-alt\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eWhy Choose Brass Hex Bar?\u003c\/h2\u003e\n\u003cp class=\"rk-lead-center\"\u003eBrass hex bar combines a wrench-ready six-sided section with fast, clean machining — the natural choice for turned fasteners and fittings.\u003c\/p\u003e\n\u003cdiv class=\"rk-feature-grid\"\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e⚙\u003c\/div\u003e\n\u003ch4\u003eFast Turning\u003c\/h4\u003e\n\u003cp\u003eBrass hex rod turns, drills and taps quickly with low tool wear for volume production.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔧\u003c\/div\u003e\n\u003ch4\u003eWrench Grip\u003c\/h4\u003e\n\u003cp\u003eSix flat faces let a spanner grip the part without slipping or rounding off.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔒\u003c\/div\u003e\n\u003ch4\u003eAnti-Rotation\u003c\/h4\u003e\n\u003cp\u003eThe hex section seats without spinning in fittings, chucks and assemblies.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🛡\u003c\/div\u003e\n\u003ch4\u003eCorrosion Resistant\u003c\/h4\u003e\n\u003cp\u003eHexagonal brass bar resists rust and moisture in plumbing and outdoor use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e✨\u003c\/div\u003e\n\u003ch4\u003eClean Finish\u003c\/h4\u003e\n\u003cp\u003eFlat hex faces polish neatly for visible nuts, fittings and decorative hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔌\u003c\/div\u003e\n\u003ch4\u003eConductive\u003c\/h4\u003e\n\u003cp\u003eBrass hex stock works for terminals, connector bodies and electrical fittings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🧪\u003c\/div\u003e\n\u003ch4\u003eHygienic Surface\u003c\/h4\u003e\n\u003cp\u003eThe copper-based surface naturally limits microbial build-up on touch hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e♻\u003c\/div\u003e\n\u003ch4\u003eRecyclable\u003c\/h4\u003e\n\u003cp\u003eBrass hex bar is fully recyclable without losing its properties.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eBrass Hex Bar Sizes, Tempers \u0026amp;

Overview\u003c\/h3\u003e\n\u003cp\u003eBrass square block is a short, solid piece of square brass stock cut to a defined length. It is supplied as a block, a brass cube or a machining blank with flat, square faces ready for further work. In trade language it is also called brass block, brass cube, brass square blank, brass machining blank, brass slug or a short-cut brass billet.\u003c\/p\u003e\n\u003cp\u003eA brass cube has three equal sides, while a brass square block has a square cross-section cut to a chosen length or height. Both begin as brass square bar that is sawn or cut into short, manageable pieces. Instead of buying a long bar and cutting it yourself, a ready brass block arrives close to the finished size, saving material and setup time. For long, continuous lengths rather than short pieces, see the Brass Square Bar range.\u003c\/p\u003e\n\u003ch4\u003eKey Characteristics of Brass Square Block\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid and dense:\u003c\/strong\u003e a full, weighty brass block with no voids, ideal for spacers, weights and sturdy components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat square faces:\u003c\/strong\u003e clean sawn or milled faces that clamp and seat squarely for CNC work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNear-net-shape:\u003c\/strong\u003e cut close to finished size to reduce waste, machining time and tool wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGood machinability:\u003c\/strong\u003e brass square blank mills, drills, taps and engraves cleanly with sharp detail.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural corrosion resistance:\u003c\/strong\u003e copper-based brass block does not rust in normal atmosphere.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttractive finish:\u003c\/strong\u003e a brass cube polishes to a warm golden shine for decorative and craft use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section rk-section-alt\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eWhy Choose Brass Square Block?\u003c\/h2\u003e\n\u003cp class=\"rk-lead-center\"\u003eReady-cut brass square block gives machinists and makers a solid, near-net-shape starting piece that is fast to finish and beautiful when polished.\u003c\/p\u003e\n\u003cdiv class=\"rk-feature-grid\"\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e⚙\u003c\/div\u003e\n\u003ch4\u003eMachining Ready\u003c\/h4\u003e\n\u003cp\u003eBrass square blank mills, drills and taps cleanly into finished parts.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e📎\u003c\/div\u003e\n\u003ch4\u003eNear-Net-Shape\u003c\/h4\u003e\n\u003cp\u003eCut close to size so you remove less brass and save setup time.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🡆\u003c\/div\u003e\n\u003ch4\u003eFlat Square Faces\u003c\/h4\u003e\n\u003cp\u003eSquare, stable faces clamp securely and seat without rocking.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e⚖\u003c\/div\u003e\n\u003ch4\u003eSolid Weight\u003c\/h4\u003e\n\u003cp\u003eDense brass block works well for weights, bases and counterweights.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🛡\u003c\/div\u003e\n\u003ch4\u003eCorrosion Resistant\u003c\/h4\u003e\n\u003cp\u003eBrass block resists rust and moisture indoors and outdoors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e✨\u003c\/div\u003e\n\u003ch4\u003ePolishes Beautifully\u003c\/h4\u003e\n\u003cp\u003eA brass cube buffs to a bright golden finish for decor and craft.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e🔌\u003c\/div\u003e\n\u003ch4\u003eConductive\u003c\/h4\u003e\n\u003cp\u003eSolid brass stock serves for contact blocks and electrical parts.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"rk-feature-card\"\u003e\n\u003cdiv class=\"rk-feature-icon\"\u003e♻\u003c\/div\u003e\n\u003ch4\u003eRecyclable\u003c\/h4\u003e\n\u003cp\u003eBrass square block is fully recyclable without losing its properties.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"rk-section\"\u003e\n\u003cdiv class=\"rk-container\"\u003e\n\u003ch2\u003eBrass Square Block Forms, Sizes \u0026amp;

Rod\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003ePure copper 110 hex bar\u003c\/strong\u003e — also called hexagonal copper bar, copper hex rod, or six-sided copper bar stock — is a solid, straight-length copper bar with a regular hexagonal cross-section, drawn from 99.9% pure copper 110. Because its six flat faces already provide built-in wrench flats, copper hex bar is the standard blank when a part must be gripped by a spanner or nut, or when a CNC shop wants to machine bolts, nuts, fittings, and valve components without milling flats onto round stock. It combines the conductivity and corrosion resistance of pure copper 110 with the practical, grip-friendly shape of hexagonal bar.\u003c\/p\u003e\n\n\u003cp\u003eHex bar is measured \u003cstrong\u003eacross the flats (AF)\u003c\/strong\u003e rather than by diameter, and every size is shown in both millimeters and inch equivalents. Pure copper 110 hex bar is supplied in standard straight lengths or cut to the exact length your job requires, ready for turning, threading, and fitting production across the United States.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Is Pure Copper 110 Hex Bar?\u003c\/h3\u003e\n\u003cp\u003ePure copper 110 is commercial-grade 99.9% pure copper chosen for high electrical and thermal conductivity, natural corrosion resistance, and good machining, forming, and joining behavior. In \u003cstrong\u003ehex bar\u003c\/strong\u003e form it is a wrought solid product with six equal flat faces and a constant hexagonal section along its full length. The six flats give two key advantages: hand tools and spanners can grip the finished part without slipping, and a lathe operator can turn a hex bar into a bolt, nut, nipple, or fitting using the full cross-section with minimal waste. Buyers search this material as “copper hex bar,” “hexagonal copper bar,” “copper hex rod,” and “copper hex stock.”\u003c\/p\u003e\n\n\u003ch3\u003eAvailable Sizes Across the Flats (AF)\u003c\/h3\u003e\n\u003cp\u003eThe table lists common pure copper 110 hex bar AF sizes with approximate inch equivalents and typical uses.

The natural mill surface can be left as machined, polished for decorative hardware, or used bare where copper’s corrosion resistance is sufficient; exposed copper develops a stable patina over time.\u003c\/p\u003e\n\n\u003ch3\u003eHex Bar vs Round, Square, and Flat Bar\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex bar\u003c\/strong\u003e is chosen when the part needs wrench flats or is a bolt, nut, or fitting — it removes the flat-milling step required with round stock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRound bar\u003c\/strong\u003e is the general blank for shafts, pins, and turned components with no gripping faces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare bar\u003c\/strong\u003e is chosen for equal-edge conductors, tooling, and square machined parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat bar\u003c\/strong\u003e is chosen for rectangular busbars, straps, and connectors with flat faces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCustom Cut Lengths\u003c\/h3\u003e\n\u003cp\u003ePure copper 110 hex bar is supplied in standard straight lengths or \u003cstrong\u003ecut to your specified length\u003c\/strong\u003e in millimeters or inches.

copper flat stock, copper busbar bar, or solid copper bus bar — is a straight, solid copper bar whose cross-section is rectangular: wider than it is thick, drawn from 99.9% pure copper 110. The broad, flat faces create large contact areas for bolted and clamped connections, which is why flat bar is the default conductor for busbars, grounding straps, shunts, switchgear links, and transformer and panel connections. It is also widely used for brackets, edging, decorative trim, and fabricated copper parts that need a flat, straight, stable section.\u003c\/p\u003e\n\u003cp\u003eFlat bar is ordered by \u003cstrong\u003ethickness (T) × width (W)\u003c\/strong\u003e, with both dimensions shown in millimeters and inch equivalents.

In \u003cstrong\u003eflat bar\u003c\/strong\u003e form it is a wrought solid product with a constant rectangular section. The defining feature is geometry: thickness is a smaller fraction of width than a square bar, but the section remains a solid bar rather than a thin, flexible strip. The two wide faces give clean, flat contact surfaces for joints and busbars, and the section is rigid enough to stand and mount without support.

pure copper 110 in the thin, formable range that bends, cuts, stamps, and solders easily. It is the material used for panels, shims and washers, roofing and flashing, backsplashes, shielding, stamped parts, heat spreaders, jewelry, and metal crafts across the United States.

In \u003cstrong\u003esheet\u003c\/strong\u003e form it is a flat-rolled product supplied in thin gauges up to the plate boundary (around 6 mm or 1\/4 inch). Thin copper sheet forms without cracking, takes clean bends and folds, stamps and shears cleanly, and solders and brazes readily, developing a long-lived protective patina outdoors. US buyers search this material as “copper sheet,” “copper sheet metal,” “pure copper sheet,” “thin copper sheet,” “copper flashing sheet,” and “copper sheet cut to size.”\u003c\/p\u003e\n\n\u003ch3\u003eThickness Range, Gauges \u0026amp; Sizes\u003c\/h3\u003e\n\u003cp\u003eThe sheet range covers thin gauges from 0.1 mm to 5 mm.
