Abstract

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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Significance and Use

These test methods are primarily intended to test for compliance with composition specifications. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.

1. Scope

1.1 This specification establishes the requirements for copper-beryllium alloy plate, sheet, strip, and rolled bar. The following alloys are specified:

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 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.
