The main added elements of zinc alloy die-casting are aluminum, copper and magnesium. Zinc alloys can be divided into deformation and cast zinc alloys according to the processing technology. Cast zinc alloys have good fluidity and corrosion resistance, and are suitable for die-casting instruments and auto parts. Shell etc.
Features of :
- (1) The proportion is large.
- (2) Good casting performance, it can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.
- (3) Surface treatment can be carried out: electroplating, spraying, painting.
- (4) When melting and die-casting, it does not absorb iron, does not corrode the pressure, and does not stick to the mold.
- (5) It has good mechanical properties and wear resistance at room temperature.
- (6) Low melting point, melting at 385℃, easy to die-casting.
