ASTM B763-08

Standard Specification for Copper Alloy Sand Castings for Valve Applications

ABSTRACT
This specification establishes requirements for copper alloy sand castings for valve applications. The castings shall conform to the chemical composition requirements specified. Mechanical properties shall be determined from separately cast test bars, and shall conform with the requirements. Brinell hardness readings shall be taken in the grip end of the tension test bar and shall be made in accordance with the specified requirements.
SCOPE
1.1 This specification establishes requirements for copper alloy sand castings for valve applications. Nominal compositions of the alloys defined by this specification are shown in Table 1.  
Note 1—This specification does not cover Copper Alloy UNS Nos. C83600, C92200, C96200, and C96400. These alloys are also used in valve applications. They are covered by the following specifications:
C83600: B 62 C92200: B 61 C96200: B 369 C96400: B 369
1.2 The castings produced under this specification are used in products which may be manufactured in advance and supplied for sale from stock by the manufacturer.  
1.3 Units—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.
