Abstract

Conductive wire with higher tensile strength was produced by in-situ deformation of copper-steel alloy. The alloy contains 11.5 wt % of low carbon steel and was cast to ingot in a vacuum inductive melting furnace. The ingot was forged to rod which then underwent multi-cold-drawing into fine electrical wire. The maximum tensile strength of the wire is 862 MPa with an electrical conductivity of 42.33 % IACS when the cold-drawing strain (η) is 6.31..
