Rapid solidification has been employed to develop high-strength/high-conductivity copper alloys, because it offers advantages not achievable by conventional ingot metallurgy practice. The effect of rapid solidification on mechanical properties and electrical conductivity on copper alloys (with and without heat treatment) has been studied. Results indicated that alloys of the Cu-Cr-Zr type, rapidly solidified and aged, show a good combination of electrical conductivity [45.82 {times} 10{sup 6} (1/{Omega} {center_dot} m)] and microhardness Vickers (24.46 {times} 10{sup 6} Pa) values. These values are superior to those of optimally aged conventional copper alloys for resistance welding electrode applications.
