This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-beryllium alloy with Copper Alloy UNS Nos. C17000 and C17200. Materials shall be processed by the following conditions: solution heat treatment, solution heat treatment and cold working, precipitation heat treatment, and mill hardening. Specimens shall adhere to specified chemical composition, grain size, and grain count requirements. Alloys shall also undergo tensile and bend tests to evaluate their conformance to tensile strength, yield strength, elongation, and Rockwell hardness requirements.
1.1 This specification establishes the requirements for copper-beryllium alloy plate, sheet, strip, and rolled bar. The following alloys are specified:
| Copper Alloy | Nominal Beryllium |
| UNS No. | Composition, % |
| C17000 | 1.7 |
| C17200 | 1.9 |
1.2 Unless otherwise specified in the contract or purchase order, Copper Alloy UNS No. C17200 shall be the alloy furnished.
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 that 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, health, and environmental practices and to determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
