1.1 This specification establishes the requirements for copper-beryllium alloy forgings and extrusions produced from the following alloys.
|Copper Alloy UNS No.||Nominal % Composition Beryllium|
Note 1—Requirements for copper-beryllium alloy rod and bar appear in Specification B 196/B 196M (Section 2).
1.2 Unless otherwise specified, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B 570 is specified without any alloy designation.
1.3 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, which are for information only and are not considered standard.
1.4 The following hazard statement pertains only to the test method portions of the specification:
1.4.1 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.
