1.1 This specification establishes the requirements for copper-beryllium alloy plate, sheet, strip, and rolled bar. The following alloys are specified:
|Copper Alloy||Previously Used Commercial||Nominal Beryllium|
|UNS No.||Designations||Content, %|
1.2 Unless otherwise required, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B 194 is specified without any alloy designation.
1.3 Units—With the exception of Grain Size values, 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 not considered standard.
1.4 The following hazard statement pertains only to the test method portions in the annex of this specification:
1.5 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.
