Cartridge Brass
70% copper 30% zinc. This is one of the most widely used of the copper zinc alloys; it is formable and ductile and possesses excellent cold working, poor hot working and poor machining properties. Rated excellent for soft soldering; good for silver alloy brazing or oxyacetylene welding and fair for resistance of carbon arc welding. The alloy develops high tensile strength with cold working. Temper is obtained by cold rolling.
