Copper clad steel wire is a metal composite material made of high-quality steel as the core wire through drawing and copper plating processes. Mainly used in the communication and electronics industries, it is a replacement product for special materials for communication wires and cables. This product has the tensile strength and toughness of steel, the conductivity of copper and the high-frequency characteristics, and has the advantages of saving copper materials and reducing costs.

The conductivity is about 25%~27%, and the DC resistivity is about four times that of oxygen-free copper. According to the calculation of the "skin effect" of wire and cable, the resistivity is equivalent to pure copper wire at high frequencies above 5MHz; 8.4. When the wire diameter and weight are equal, the tensile strength is 1/4 higher than that of the same type, which effectively solves the problem of wire breakage in the production process, further improves production efficiency, and reduces production costs.
