scope:

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 1.² 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 492, B 505, B 763, B 770, and B 806.

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.

The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

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.
