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

SCOPE
1.1 This specification establishes the requirements for copper and copper alloy die forgings produced by the hot pressing method. The following copper and copper alloys are included:
1.2 UnitsValues stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.Note 1
Nominal composition and relative forgeability ratings are given in . 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.
The following safety caveat pertains only to Section 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.
