(Specification)Standard Specification for Copper-Alloy Die Castings
Standard Specification for Copper-Alloy Die Castings
ABSTRACT
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.
SCOPE
1.1 This specification establishes the requirements for copper-alloy die castings. The alloys specified are Copper Alloy UNS Nos. C85470, C85700, C85800, C86500, C87800, C99700, and C99750.2
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
