Generally supplied as extruded / as manufactured.

CuZn40Pb2 is for applications where an alloy with lower lead content than CW614N is needed, the reference material for hot working. The mean lead content provides good machinability of the drop forged part.
Because of its composition the alloy is also suited for the production of drawn, complex profile shapes. The alloy has very good forge ability and good machinability

Machining brass is generally quite resistant against organic substances as well as neutral or alkaline compounds. Stress corrosion cracking and dezincification in warm, acidic waters should be taken into account, especially in an ammoniacal atmosphere and whilst under mechanical stress
