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