This specification covers requirements for copper alloy sand castings for general applications. The components part casting may be manufactured in advance and supplied from stock. The castings shall conform to the compositional requirements for named elements specified. Mechanical properties of copper alloys such as tensile strength, yield strength, and elongation shall be determined. The castings shall not be repaired, plugged, welded, or burned in.

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 documents as shown in Table 1.

Note 1—Other copper alloy castings are included in the following ASTM specifications: B 22, B 61, B 62, B 66, B 67, B 148, B 176, B 271, B 369, B 427, B 505/B 505M, B 763, B 770, and B 806.

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.
