Description

Withdrawn Rationale:

This specification establishes the requirements for copper-cobalt-beryllium alloy (UNS No. C17500) and copper-nickel-beryllium alloy (UNS No. C17510) forgings and extrusions.

Formerly under the jurisdiction of Committee B05 on Copper and Copper Alloys, this specification was withdrawn in April 2010 and replaced by Specification B870 on Copper-Beryllium Alloy Forgings and Extrusions Alloys (UNS Nos. C17500 and C17510).


1. Scope

1.1 This specification establishes the requirements for copper-cobalt-beryllium alloy (UNS No. C17500) and copper-nickel-beryllium alloy (UNS No. C17510) forgings and extrusions.

1.2 The intent is to provide a system of interchangeable alloys.

1.3 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.

1.4 The following safety hazard caveat pertains only to the test method(s) described in 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.
