Frequently Asked Questions
Warum ist es called 'cartridge brass'?
Der 70/30 Cu-Zn composition war established in der 19th century für rifle und pistol cartridge cases because es combines der deep-drawing formability needed zu produce der case body mit sufficient strength zu withstand firing pressure. Es remains der standard für ammunition cases today.
