Copper Clad Steel Wire

What is Copper Clad Steel Wire?

Copper clad steel wire (CCS) is a composite wire material that combines the conductivity of copper with the strength and durability of steel. It consists of a steel core surrounded by a thin layer of copper. The result is a wire that provides the mechanical properties of steel, such as high tensile strength and resistance to stretching or breaking, along with the superior electrical conductivity of copper.
