Mechanical Properties of Copper Based Alloys
Tabulated in accordance with the Unified Numbering System for Metals and Alloys (UNS), Society of Automotive Engineers, Warrendale, Pa., 1975. This reference contains the cross reference numbers for AISI, ASTM, FED, MIL SPEC, and SAE specifications. All yield strength are by 0.5 percent offset method. Multiply strength in MPa by 0.145 to get strength in kpsi.
