(Specification)Standard Specification for General Requirements for Copper Alloy Castings
Standard Specification for General Requirements for Copper Alloy Castings
ABSTRACT
This specification establishes the general requirements common to copper alloy castings of UNS Nos. C94700, C95300, C95400, C95410, C95500, C95520, and C96800. Materials shall be sampled and prepared, then tested accordingly to examine their conformance to mechanical (tensile and yield strength, hardness, and elongation), electrical (resistivity and conductivity), dimensional, chemical composition, and grain size requirements. In the event of conflict between this specification and the individual casting product specifications, the requirements of the casting specification shall take precedence.
SIGNIFICANCE AND USE
For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.
SCOPE
1.1 This specification establishes general requirements common to ASTM copper alloy casting specifications B22, B61, B62, B66, B67, B148, B176, B271, B369, B427, B505/B505M, B584, B763, B770, and B806. These requirements apply to the casting specifications to the extent referenced therein.
1.1.1 In the event of conflict between this specification and a casting specification, the requirements of the casting specification shall take precedence.
1.2 The chemical composition and other requirements not included in this specification shall be prescribed in the casting product specifications.
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.
1.4 No precise quantitative relationship can be stated between the properties of the metal in various locations of the same casting or between the properties of castings and those of a test bar casting from the same metal. (See Appendix X1.)
