    Pure Copper Wire

    The pure copper wires we offer have a copper content of over 99.95%, and are designed to meet diverse industrial needs. Our pure copper wires are available in various configurations, including single wire, stranded wire, multi-strand wire rope, and parallel multi-wire, with diameters ranging from 0.02mm to 8.0mm. The manufacturing process to obtain quality pure copper wires includes drawing, annealing, stranding, electroplating, and insulation, ensuring consistent quality and adaptability for different applications.

    Wire Drawing Range
    • 0.460mm→0.265mm (6 drawing dies)
    • 1.070mm→0.432mm (10 drawing dies)
    • 0.03658mm→0.02135mm (14 drawing dies)
