This specification covers requirements for copper alloy sand castings for general applications. The components part casting may be manufactured in advance and supplied from stock. The castings shall conform to the compositional requirements for named elements specified. Mechanical properties of copper alloys such as tensile strength, yield strength, and elongation shall be determined. The castings shall not be repaired, plugged, welded, or burned in.
Область применения1.1 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 1.2 This is a composite specification replacing former documents as shown in Table 1.
