Pure copper wire conductive copper filament

Pure copper wire plays a vital role in electrical, electronic, and high-end signal transmission. Engineered for peak performance, our premium Bare Copper Wire, Enameled Magnet Wire, and OCC Copper Wire offer exceptional electrical conductivity, superior mechanical properties, and precision manufacturing. They perfectly meet the rigorous demands of everything from basic power transmission and precision coil winding to audiophile-grade lossless signal conduction.

Product Form Composition Key Characteristics Typical Applications
Bare Copper Wire
High-Purity OFC / Solid Copper
 Cu: ≥ 99.9%
High purity, uninsulated		 Features outstanding electrical and thermal conductivity, a smooth surface finish, and excellent ductility. Easy to cold crimp, solder, and draw further. The foundational conductor for all electrical connections.
  • Architectural & industrial grounding
  • Power cables & coaxial cable cores
  • Electronic component connecting pins
Enameled Wire
Magnet Wire
 Copper Core (Cu ≥ 99.9%)
+ Polyurethane/Polyester insulation		 Uniformly coated with a high-strength insulating enamel film over high-quality pure copper. Offers high dielectric breakdown voltage, excellent thermal class ratings (e.g., 130°C–220°C), and superior scratch and winding resistance.
  • Motor & generator windings
  • Power transformers & inductors
  • Solenoid valves, relays & micro-motors
OCC Copper Wire
Ohno Continuous Casting
 Cu: ≥ 99.999% (5N-6N)
Single-crystal structure		 Manufactured using the specialized Ohno Continuous Casting (OCC) process to eliminate internal metal "grain boundaries." Drastically reduces capacitance/inductance effects and signal attenuation, delivering an ultra-pure, lossless signal path.
  • Audiophile Hi-Fi audio & headphone cables
  • High-speed data cables (HDMI/DP)
  • Aerospace & precision medical wiring
