ZA alloy is based on Zn and composed of Al, Cu, Mg added as alloying elements. It is a kindof environmental friendly material that possesses characteristics of high strength, better plasticity,excellent wear resisting property, low friction coefficient and high specific strength, low meltingpoint and no magnetic. ZA alloy has been widely applicated in the fabrication of mechanical partsand models, such as bearing, axle sleeve, pressing plate and turbine. However, the joiningproblem of ZA alloy that hasnt been solved has limited its application in some fields.
