Composed of a steel core with copper cladding, the steel wire gives the wire its strength and the consistent layer of copper
provides electrical conductivity and resistance to corrosion.
To manufacture Copperclad Steel Wire, carbon steel (low, high strength and extra high strength) is bonded with a uniform
layer of oxygen-free coppercladding to achieve 30% and 40% IACS (International Annealed Copper Standard) conductivities.
