Abstract
Copper alloys for electrical applications, particularly in the computer industry, and a process for making the copper alloys. The copper alloys contain 13-15% by weight of zinc, 0.7-0.9% by weight of tin, and 0.7-0.9% by weight of iron, the balance being copper. The low tin and iron content and high zinc content provide high tensile and yield strengths, a high conductivity, and a low cost for the copper alloys.
