Standard Specification for Commercial Bronze Strip for Bullet Jackets
ABSTRACT
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.
SIGNIFICANCE AND USE
For purposes of determining compliance with the specified property limits for the properties listed in the following table, an observed value of a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E 29: PropertyRounded Unit for Observed or Calculated Value Chemical composition nearest unit in the last right-hand place Hardness of figures of the specified limits. Tensile strength nearest ksi (nearest 5 MPa) Grain size: Up to 0.055 mm, incl nearest multiple of 0.005 mm Over 0.055 to 0.160 mm, incl nearest 0.01 mm Elongation: 5 % and over nearest 1 %
SCOPE
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.
