Abstract
A copper alloy which is high in strength and electroconductivity is manufactured by casting, without chill casting, a copper alloy mass substantially consisting of copper and containing 0.2 to 1.5% by weight of chromium and 0.01 to 0.5% by weight of tin, hot working the cast copper alloy mass, then cooling, not slowly, the hot worked alloy mass without being subjected to any solid solution treatment, further cold working the cooled alloy mass, and thereafter subjecting the cold worked alloy mass to an aging treatment.
