Medium Pure Copper 110 Round Bar & Rod — Solid Copper Rod

Medium Pure Copper 110 Round Bar & Rod — Solid Copper Rod

Medium pure copper 110 round bar — also searched as solid copper rod, medium-diameter copper round bar, or machinable copper rod — is the workhorse size range of solid straight copper bar drawn from 99.9% pure copper 110. It covers the middle diameters where most engineering, electrical, and fabrication work takes place: large enough to turn, thread, drill, and mill into real components, yet small enough to cut, bend, and handle on standard workshop equipment. This is the most commonly ordered pure copper 110 round bar range for shafts, connectors, terminals, grounding parts, electrode components, and general machined copper parts across the United States.

Every stick is a solid, non-hollow round section supplied straight, with diameters shown in both millimeters and inch fractions so the same rod matches metric drawings, US inch-based prints, and common fractional stock sizes. Medium pure copper 110 round bar can be ordered in standard lengths or cut to the exact length your job requires.

What Is Medium Pure Copper 110 Round Bar?

Pure copper 110 is commercial-grade 99.9% pure copper, chosen for its high electrical and thermal conductivity, natural corrosion resistance, and excellent forming and machining behavior. In round bar (round rod) form it is a wrought product with a constant circular cross-section along its entire length. The medium range fills the gap between thin craft-size rod and heavy industrial bar: it is the default choice when a part needs real cross-section for current carrying, torque, or threading, but does not require the mass of large-diameter copper bar.

US suppliers and buyers use bar and rod interchangeably for this stock — “medium copper rod,” “solid copper round bar,” and “copper bar stock” all point to the same product.

Available Diameters in the Medium Range

The table lists common medium pure copper 110 round bar diameters with approximate inch equivalents. Choose diameter as the product variant, then specify your required length; set variants to the exact diameters you stock.

Smaller diameters are listed under small round bar (2–6mm), and heavier sections under large round bar (26–100mm). Hexagonal, square, and flat sections are available in the copper bar and rod collection.

Key Properties of Pure Copper 110 Medium Round Bar

Why the Medium Diameter Range Is the Workhorse

• Right cross-section for real components — shafts, studs, bolts, and connector bodies need more metal than small rod provides.
• High current capacity in compact form — widely used for terminals, lugs, switchgear links, and grounding conductors.
• Standard equipment friendly — fits common chucks, collets, dies, and bench tools without industrial-scale machinery.
• Threading and tapping stock — solid round copper rod is the standard blank for custom copper bolts, posts, and threaded fittings.
• Metric and fractional inch coverage — diameters line up with both mm prints and common US fractional sizes.
• Cut-to-length with no surplus — order the exact number of sticks or pieces your batch needs instead of full bundles.

Common Applications

Medium pure copper 110 round bar and solid copper rod are widely used for electrical connectors and connector bodies, cable lugs and terminals, contact fingers and contact carriers, switchgear and control-gear components, busbar taps and busbar connectors, grounding rods, grounding posts and bonding conductors, transformer and motor connections, welding electrode holders and electrode tips, resistance-welding parts, shafts, spindles, pins and axles, custom bolts, studs, screws and threaded fittings, bushings, spacers and standoffs, valve and pump internals, heat-conducting posts and heat-spreader pins, anodes and cathode bars, dip-brazing and soldering fixtures, RF and antenna parts, chemical plant hardware, marine fittings, jewelry and sculptural armatures, and general CNC turning, milling, and fabrication of conductive copper parts.

Working & Fabrication Notes

Medium pure copper 110 round bar cuts with standard metal-cutting bandsaws and abrasive discs and machines with sharp high-speed steel or carbide tooling. It can be drilled, tapped, turned, knurled, and threaded for custom fasteners and fittings; it bends cold with suitable radii and can be annealed with heat when tighter forming is required. For joining, the clean solid section solders and brazes easily, making it well suited to low-volume electrical assemblies and repair work as well as production machining.

Custom Cut Lengths

Medium pure copper 110 round bar is supplied in standard straight lengths or cut to your specified length, in millimeters or inches. Repeated identical pieces — connector blanks, pin stock, stud blanks, or busbar links — can be cut from the same diameter rod so parts arrive ready for final machining. Select diameter from the variant list and state the required length when ordering; non-standard diameters and heavier sections can be noted as custom requirements with longer handling time.
