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.

1.1 This specification establishes requirements forcopper alloy sand castings for valve applications. Nominalcompositions of the alloys defined by this specification are shownin Table 1.

Note 1—Thisspecification does not cover Copper Alloy UNS Nos. C83600, C92200,C96200, and C96400. These alloys are also used in valveapplications. 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 specificationare used in products which may be manufactured in advance andsupplied for sale from stock by the manufacturer.

1.3 UnitsThe values stated in either SI unitsor inch-pound units are to be regarded separately as standard. Thevalues 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-conformancewith the standard.
