Standard Specification for Copper-Beryllium Alloy Forgings and Extrusions (UNS Nos. C17000 and C17200)
Standard Specification for Copper-Beryllium Alloy Forgings and Extrusions (UNS Nos. C17000 and C17200)
ABSTRACT This specification establishes the requirements for copper-beryllium alloy (UNS nos. C17000 and C17200) forgings and extrusions. The material of manufacture shall be cast or wrought billet of C17000 or C17200 of such purity and soundness as to be suitable for processing into the products prescribed. The product shall be manufactured by hot working and heat treating as may be necessary to meet the properties specified. The product composition shall conform to the chemical requirements specified. The standard temper designations available under this specification and as prescribed in Classification B 601 are solution heat-treated TB00 (A) and precipitation heat-treated TF00 (AT). The product in the TF00 (precipitation-hardened (AT)) condition shall have a microstructure with a minimum of second phase (beta) constituents. When present, beta shall be fine and well dispersed. The product furnished under this specification shall conform to the prescribed hardness requirements. Tensile properties shall be determined in accordance with test methods E 8. SCOPE 1.1 This specification establishes the requirements for copper-beryllium alloy forgings and extrusions produced from Copper Alloy UNS Nos. C17000 and C17200. 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 an 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 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 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.
ASTM B570-22 is the standard specification developed by ASTM International for copper-beryllium alloy forgings and extrusions, specifically for UNS C17000 and C17200. This standard establishes comprehensive requirements for the chemical composition, manufacturing processes, mechanical properties, and tolerances of these high-performance copper alloys. Products covered by ASTM B570-22 are valued for their exceptional strength, electrical conductivity, and resistance to fatigue and corrosion, making them critical materials in demanding applications.
Copper-beryllium alloy forgings and extrusions produced as per ASTM B570-22 are widely used in industries where a unique combination of strength, electrical conductivity, and durability is essential. Common application areas include:
