Standard Specification for Copper Alloy Sand Castings for Valve Applications
The following bibliographic material is provided to assist you with your purchasing decision:
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 1.2
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: B62 C92200: B61 C96200: B369 C96400: B369
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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
