Products Bare Copper Wire
Bare Copper Wire
Uncoated electrolytic copper, cadmium-free. Used in overhead lines, light poles, heavy appliances and machinery.
Not every application needs enamel. We draw bare copper wire from the same 99.99% ETP cathode, supplied hard-drawn, half-hard or fully annealed to suit the job, and free of cadmium and other restricted metals. Conductivity is a minimum of 100% IACS and the surface is clean and bright, ready for tinning, stranding or direct winding.
Bare wire is available in single sizes on spools and in bulk coils, and we can supply it as the conductor for your own insulating or stranding operations.
