ASTM B823-15

Standard Specification for Materials for Copper Base Powder Metallurgy (PM) Structural Parts

SCOPE
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 cubic centimetre (g/cm3) unit is the industry standard, the values stated in inch-pound units are to be regarded as the standard. Values in SI units result from conversion. They may be approximate and are for information only.

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.
