|Publication Date:||1 October 2016|
|ICS Code (Copper products):||77.150.30|
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:
|Copper or Copper Alloy|
|C27453||copper zinc alloy|
|C36500||leaded Muntz metal|
|C37000||free-cutting Muntz metal|
|C48200||medium leaded naval brass|
|C48500||leaded naval brass|
|C62300||aluminum bronze, 9 %|
|C65500||high-silicon bronze (A)|
|C67500||manganese bronze (A)|
|C67600||. . .|
|C77400||nickel silver, 45-10|
1.2 Units-The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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: Guidelines for design and development of forgings are included in Appendix X2.
Note 3: Wrought product intended for hot forging is described in Specification B124/B124M.
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.
