Standard Specification for Copper-Beryllium Alloy (UNS Nos. C17000 and C17200) Forgings and Extrusions

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 the following alloys.    
Copper Alloy UNS No.  
Nominal % Composition
Beryllium    
C17000
C17200

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.
