This specification covers the standard for commercial bronze strip for manufacture of bullet jacket cups and ammunition components from copper alloy UNS No. C22000. The specimens shall be manufactured by such hot working, cold working, and annealing processes to produce a uniform wrought structure. Each specimen shall be subjected to tension test and Rockwell hardness test. In addition to tensile properties for strips, purchaser may also specify grain size. If specimens fail to conform to the prescribed specification, analysis shall be made on a new composite sample.

1.1 This specification establishes general requirements for (commercial bronze) strip for manufacture of bullet jacket cups and ammunition components from Copper Alloy UNS No. C22000.

1.2 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.
