ASTM B929-17

Standard Specification for Copper-Nickel-Tin Spinodal Alloy Rod and Bar

ABSTRACT
This specification covers the requirements for UNS C72900 copper-nickel-tin alloy rods and bars. Products should be manufactured by hot working, cold working, and annealing processes to produce a uniform wrought structure in the finished product. Each product should then be hot or cold worked to the finished size, and if required, should be subsequently annealed to meet the specified temper properties. The tensile strength and Rockwell hardness values from prescribed tests on the products should fall within the required range.
SCOPE
1.1 This specification establishes the requirements for copper-nickel-tin alloy rod and bar. The following alloy is included:    
Copper Alloy
UNS No.  
Nominal Composition, Weight %  
Copper  
Nickel  
Tin  
C72900  
77  
15  
8  
1.2 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.  
1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification.  
1.4 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.  
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.
