Copper coated steel wire is composed by core steel wire and outside coated copper. They are diveded into kinds based on conductivity, i. E. 21%IACS, 30%IACSand 40%IACS, and on the base of annealing it can be: Soft(A), hard(hs), and extremely hard(ehs), the company can produce the wire with conductivity and tensile strength requireed by customer the diameter of copper coatedsteel wire is whithin the sope of 0. 10mm-2. 00mm based on the requirement of customer, if processed further, the silvering copper-coated steel wire and tinning copper-coated steel wire are cutputted.
