In this study, the microstructural evolution and various characteristics of Al-20 similar to 45wt%Zn alloys were investigated. In terms of microstructure, as the amount of Zn addition to the alloys increased, the a-phase size decreased and the a-hi non-equilibrium solidification phase fraction increased. Also, increasing Zn content improved the wear resistance of the alloys, but reduced the damping capacity and toughness of the alloys. Their physical properties of the Al-Zn alloy with high Zn content, specifically the wear resistance and toughness, were superior to those of commercial ALDC12 alloys for die-casting. Based on these results, we considered the possibility of application of the developed Al-Zn alloy as a structural material.
