High strength, high conductivity copper alloy wire and a cable therefrom and method for manufacturing same, wherein the copper alloy contains chromium from 0.15-1.30%, zirconium from 0.01-0.15% and the balance essentially copper. The alloy wire is heat treated, cold worked to an intermediate gage, heat treated, cold worked to final gage, and finally heat treated.

Copper alloy wire and cable and method for preparing same

High strength, high conductivity copper alloy wire and a cable therefrom and method for manufacturing same, wherein the copper alloy contains chromium from 0.15-1.30%, zirconium from 0.01-0.15% and the balance essentially copper. The alloy wire is heat treated, cold worked to an intermediate gage, heat treated, cold worked to final gage, and finally heat treated. A major portion of the chromium and zirconium are present as precipitated, sub-micron sized particles in a copper matrix. In addition, the wire has a gage of 0.010 inch or less and a tensile strength of at least 55% ksi, an electrical conductivity of at least 85% IACS, and a minimum elongation of 6% in 10'.
