Standard Specification for Copper Alloy Bullet Jacket Cups

ABSTRACT
This specification covers bullet jacket preform cups made from UNS C22000 wrought copper alloy used for processing Types I-IV and Classes I-II bullet jackets. This standard contains information on chemical composition, grain size and testing requirements for the preform cups.
SIGNIFICANCE AND USE
For the purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value, or a calculated value, shall be rounded as indicated in accordance with the rounding method of Practice E29.
PropertyRounded Unit for Observed or Calculated Value Chemical compositionNearest unit in the last right-hand significant digit used in expressing the limiting value Grain sizeNearest multiple of 0.005 mm
SCOPE
1.1 This specification establishes the requirements for bullet jacket preform cups produced of Copper Alloy UNS No. C22000 for processing into bullet jackets of the following types and classes:
1.1.1 Type I—Caliber 0.30.
1.1.2 Type II—Caliber 0.45.
1.1.3 Type III—Caliber 0.50.
1.1.4 Type IV—As specified in the contract or order.
1.1.5 Class I—Not annealed.
1.1.6 Class II—Annealed.
1.2 Units—Values stated in inch-pound units are to be regarded as standard, except for grain size, which is given in SI units. The values in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
