HMn58-2 マンガン黄銅 日本

High corrosion resistance in sea water, superheated steam and chloride, but corrosion cracking tendency; good mechanical properties, low thermal conductivity and electrical conductivity, easily pressure processing in hot state, workability in cold state, which is a kind of widely used brass.
Hmn58-2 manganese brass is used for important components under corrosive conditions and low current industrial components.
