Specification for
Copper Alloy Sand Castings for General Applications
1. Scope
1.1 This specification covers requirements for copper alloy sand castings for general
applications. Nominal compositions of the alloys defined by this specification are shown in Table
1. This is a composite specification replacing former docu- ments as shown in Table 1.
NOTE 1Other copper alloy castings are included in the following ASTM Specifications:
B22/B22M, B61, B62, B66, B67, B148, B176, B271/B271M, B369, B427, B505/B505M, B763/B763M,
B770, and B806.
1.2 Component part castings produced to this specification may be manufactured in advance and
supplied from stock. In such cases the manufacturer shall maintain a general quality
certification of all castings without specific record or date of casting for a specific casting.
1.3 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.
