Copper Alloys, BrassCW505L (CZ106) Sheet

An alpha brass alloy often referred to as a cartridge brass, with less than 37% zinc.

The CW505L/CZ106 is an alpha brass sometimes referred to as cartridge brass, with an approximate zinc content of 30% with the balance of the composition being copper.

CW505L/CZ106 exhibits an excellent combination of strength and ductility for the alpha phase brasses. This grade is used for its outstanding deep drawing properties and excellent cold workability.
