Historical (view previous versions of standard)
This specification establishes the requirements for copper-alloy die castings and covers Copper Alloy UNS Nos. C85700, C85800, C86500, C87800, C99700, and C99750. The material shall conform to the chemical composition requirements prescribed for copper, tin, lead, zinc, iron, nickel, cobalt, aluminum, manganese, silicon, antimony, sulphur, and phosphorus. Unless specified, acceptance of die castings under this specification shall not depend on mechanical properties determined by tension or impact tests. Requirements for sampling for chemical analysis, dimensions, mass, internal soundness, and pressure tightness are given.
