CuZn33, as well as CuZn28 and CuZn30 is combining excellent cold forming properties with good mechanical strength. CuZn30 has good hot forming properties and excellent soldering and brazing properties. Due to the outstanding deep drawing properties CuZn33 and the other two mentioned alloys are called “deep-draw” or “cartridge” brass. We produce qualities with grain sizes below 5 μm if needed. The alloy type is listed in the USA by EPA to have good antimicrobial properties.
