Copper Wire Rod Our Copper Wire Rod is manufactured from high-purity copper cathode (Grade A) using the Continuous Casting and Rolling (CCR) process. It offers excellent electrical conductivity, a bright and oxide-free surface, and is ideal for use in wire and cable manufacturing, industrial conductors, and electrical applications. Strict quality control is applied at every production stage, and a chemical and physical analysis report can be provided for each production batch. The rods are available in 6 mm and 8 mm diameters, supplied in 2–4 ton coils.
