(Specification)Standard Specification for Copper Alloy Permanent Mold Castings for General Applications
Standard Specification for Copper Alloy Permanent Mold Castings for General Applications
ABSTRACT
This specification covers the requirements for UNS C95300, C95400, C95410, C95500, C95800, C87500, C87800, C87850, and C89540 copper alloy permanent mold castings for general applications. UNS C95800 copper alloy used in sea water applications should be heat treated for better corrosion resistance. In general, alloys included in this specification are weldable. Mechanical properties like the tensile strength, yield strength and elongation are determined from separately cast test bar castings and should conform to the specified requirements.
SCOPE
1.1 This specification establishes requirements for copper alloy permanent mold castings for general applications. Nominal compositions of the alloys under this specification are shown in Table 1.
1.2 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
