Leaded Brass C34500
UNS C34500
Description
Leaded Brass C34500, also known as CZ131 and CW601N, is the brass with high machining ability. The addition of lead will result in increased machining ability with good strength and atmospheric corrosion resistance, as well as the pressure tightness by sealing the shrinkage pores. It exhibits an excellent capacity for being machined, thread rolled & formed. This alloy has a poor capacity to be hot worked. if cold working or extensive machining is necessary, it is recommended that this be followed by stress relieving at 500 degrees for 1.5 hours to reduce the possibility of stress corrosion cracking.
