About brass copper alloys
Brass is the copper-zinc alloy family. C26000 (cartridge brass, 70/30) is the standard for deep drawing, ammunition cases, and decorative work. Higher-zinc brasses such as C36000 (free-cutting) are the standard for screw-machine work. Lead-free brass is increasingly required for potable-water service.
