MAIN CHARACTERISTICS
This alloy has a good resistance to water, water vapour, different saline solutions, many organic liquids. Industrial, maritime and country air. CuZn30 tends to stress corrosion cracking, when in contact with e.g. hydrous ammonia, ammoniac salt or amine and others. Trough a heat-treatment of semi-finished or finished products the risk of stress corrosion can be reduced. Not particularly resistant to aAcids, hydrous sulphur components.
CuZn30, as well as CuZn28 and CuZn33 is combining excellent cold forming properties with good mechanical strength. The alloy has good hot forming properties and excellent soldering and brazing properties. Due to the outstanding deep drawing properties CuZn30 and the other two mentioned alloys are called “deep-draw” or “cartridge” brass.
