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''.
