Scope

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
C17000 C17200	1.7 1.9

Note 1: Requirements for copper-beryllium alloy rod and bar appear in Specification B196/B196M (Section 2).

1.2 Unless otherwise specified, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B570 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 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:

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 to determine the applicability of regulatory limitations prior to use.
