MAIN CHARACTERISTICS
Characterized by a good resistance to fresh water, neutral or alkaline solutions, organic compounds as well as land, sea, and industrial atmosphere. Not particularly resistant to acids, hydrous sulphur compounds, hydrous ammonia.
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 brass for “deep-draw”.
