General Description Engraving brass is traditionally used for machine engraved name plates due to its combination of high strength and free machining characteristics. It is an alpha / beta brass with a duplex structure which renders it unsuitable for acid etched work, for which the single phase brasses such as C26000 (70/30 brass) are preferable.
C35600 weathers to the warm brown bronze tone which is desirable for name plates.
C37000 is also available, with lower (0.9–1.4%) lead content. It has excellent free cutting properties, but machinability is only 70% of C35600.
Typical applications are engraved name plates and plaques, appliance trim, clock components, builders hardware, gear meters, free machining sheet and plate.
Phase Diagram & Mechanical Properties
C35600 has good corrosion resistance to weathering and fair resistance to many waters. There is some risk of failure by dezincification.
C35600 should not be used in contact with ammonia, ammonia compounds or amines, as it may suffer stress corrosion cracking. It is more susceptible to stress corrosion and dezincification than the single phase high copper brasses, but these are seldom a serious problem in atmospheric conditions.
