ASTM B129

This specification establishes the requirements for annealed cartridge brass cups produced of Copper Alloy UNS No. C26000 for processing into for Type I and II cartridge cases, which are for small arms cartridge case cups and for artillery cartridge case cups, respectively. The material of manufacture shall be annealed plate, sheet, strip, or disks of wrought Alloy UNS No. 26000 processed to produce even-topped cups. The material shall be blanked and cupped to meet the cup dimensions specified, and subsequently annealed. The annealed cups shall be pickled, washed, and dried. The chemical and the grain size requirements are specified.
