What is copper clad steel wire used for?

Copper Clad Steel (CCS) is a composite conductor material consisting of steel core surrounded by copper.

Copper provides conductivity and steel provides strength to the conductor.

The most common grade of CCS used for electrical conductors has a nominal 40% IACS conductivity.

CCS is suitable for applications requiring high strength and moderate conductivity.

Copper-clad steel is also suitable for high-frequency signal applications because high-frequency currents travel primarily in the outer skin of the conductor.

CCS is available bare or plated with silver, nickel or tin.

  • ASTM B227 – Standard Specification for Hard-Drawn Copperclad Steel Wire
  • ASTM B228 – Standard Specification for Concentric-Lay-Stranded Copperclad Steel Conductors
  • ASTM B910 – Standard Specification for Annealed Copperclad Steel Wire

Among them, the steel can be low, high strength and extra high strength carbon steel.

Usually copper clad steel wire can reach 30% and 40% IACS conductivity.

Common sizes are available in 1, 3, 7 and 19 strand cables.

It is also possible to add a sheath on the basis of the conductor.

  • While maintaining the high strength of steel, it exhibits the same corrosion resistance as copper.
  • Stronger than copper and more resistant to mechanical damage.
  • Reduces the risk of damage during installation.
  • Mild steel core provides maximum flexibility while maintaining high strength.
  • Easy handling and installation without special tools or equipment.
  • Very low scrap value to prevent theft.
