Zinc alloys are alloys based on zinc and composed of other elements. Common alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy recovery and remelting of disability materials; But the creep strength is low and the size change is easy to occur due to natural aging. Prepared by melting, die casting or pressure processing.
According to the manufacturing process can be divided into cast zinc alloy and deformed zinc alloy. The main additive elements of zinc alloys are aluminum, copper and magnesium. Zinc alloys can be divided into deformation and casting zinc alloys according to processing technology. The cast zinc alloy has good fluidity and corrosion resistance, and is suitable for die casting instruments, auto parts shells, etc.
