scope:

This specification establishes requirements for copper alloy² permanent mold castings for general applications. Nominal compositions of the alloys under this specification are shown in Table 1.

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.

² The UNS system for copper and copper alloys (see Practice E 527) is a simple expansion of the former standard designation system accomplished by the addition of a prefix "C" and a suffix" 00". The suffix can be used to accommodate composition variations of the base alloy.

*A Summary of Changes section appears at the end of this standard.
