Zinc alloy is an alloy composed of zinc and other elements. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has a low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and waste materials are easy to recycle and remelt; but the creep strength is low and it is easy to cause dimensional changes due to natural aging. It is prepared by melting method and die-casting or pressure processing.
