1.1 This specification covers a variety of copper base powder metallurgy (PM) structural materials, including those used in applications where high electrical conductivity is required. It includes a classification system, or material designation code. With the classification system, this specification includes chemical composition and minimum tensile yield strength.

Note 1 - Paragraphs 6.1 and 8.1 govern material classification by the designation code. The classification system is explained in the Appendix.

Note 2 - Materials classified as C-0000 are expected to be used in applications where high electrical conductivity is required.

1.2 With the exception of density values, for which the g/cm³ unit is the industry standard, the values stated in inch-pound units are to be regarded as the standard. The stated SI values are converted in accordance with IEEE/ASTM SI 10 and are for information only.
