ABSTRACT
This specification establishes the requirements for copper and copper die forgings produced by hot pressing method. The forgings included here are designated with the following Copper or Copper Alloy UNS Nos.: C11000 (copper), C14500 (copper-tellurium alloy), C14700 (copper-sulfur alloy), C36500 (leaded Muntz metal), C37000 (free-cutting Muntz metal), C37700 (forging brass), C46400 (naval brass), C48200 (medium leaded naval brass), C48500 (leaded naval brass), C61900 (aluminum bronze), C62300 (9% aluminum bronze), C63000 and C63200 (aluminum-nickel bronze), C64200 (aluminum-silicon bronze), C64210 (6.7% aluminum-silicon bronze), C65500 (high-silicon bronze), C67500 (manganese bronze), C67600, C69300 (copper-zinc-silicon alloy), C70620 (90% copper-10% nickel alloy), C71520 (70% copper-30% nickel alloy), and C77400 (45% nickel-10% silver alloy). The materials for manufacture shall be rods, billets, or blanks of such purity and soundness as to be suitable for processing by hot pressing. Products shall be tested to examine their conformance to mechanical (tensile and yield strengths, and elongation), dimensional, and chemical composition requirements.
SCOPE

1.2 Units—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.
Note 1—Nominal composition and relative forgeability ratings are given in Appendix X1. Copper-nickel alloys C70620 and C71520 are intended for welded applications with seawater exposure.
Note 2—Wrought product intended for hot forging is described in Specification B 124/B 124M.
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 concerns, 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.
