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.
