ASTM B283-99a

Standard Specification for Copper and Copper-Alloy Die Forgings (Hot-Pressed)

SCOPE
1.1 This specification covers the requirements for copper and copper alloy die forgings produced by the hot pressing method. The following copper and copper alloys are included: Copper or Copper Alloy UNS No. 2 Name C11000 copper C14500 copper-tellurium C14700 copper-sulfur C36500 leaded Muntz metal, uninhibited C37700 forging brass C46400 naval brass C48200 medium leaded naval brass C48500 leaded naval brass C61900 aluminum bronze C62300 aluminum bronze, 9 % C63000 aluminum-nickel bronze C63200 aluminum-nickel bronze C64200 aluminum-silicon bronze C64210 aluminum-silicon bronze, 6.7 % C65500 high-silicon bronze (A) C67500 manganese bronze (A) C67600 ... C77400 nickel silver, 45-10
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.3 The following safety caveat pertains only to Section 10 of this specification: This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
Note 1- Nominal composition and relative forgeability ratings are given in Appendix X1.
