Abstract: High-Strength, High-Conductivity Copper Alloys Cu-Ni-Sb alloys have been discovered having a two-phase or multiphase state at low levels of antimony, and alloys in such state have high strength, high ductility, and high electrical conductivity. Tensile strengths in the range of 80,000- 160,000 psi have been achieved, and electrical conductivity in the range of 30-65 percent of the conductivity of copper. Alloys of the invention can be made by processing involving homogenizing, rapid cooling, cold working, and aging; for maximized electrical conductivity, dual combined steps of cold working and aging are beneficial.
