Aluminum-based alloy are one of the most alloy beneficial in the industry. Therefore, the research is done on the effect of Zn addition on Al alloys fabrication using powder metallurgy method. The composition of 0% and 10% Zn with sintering temperature varied: 550oC, 600oC, and 650oC respectively at that temperature held for 1 hour. Characterization includes: measurement of hardness, SEM analysis, and XRD analysis. The result of XRD analysis from the results of the rietveld refinement phase using the match program it is found several phases is Al, Zn and ZnO. From the result of SEM analysis it is found that the reaction between Zn and Al so as to form solid solution phase on the addition of 10% Zn with 650oC sintering temperature. From the result of characteristic of mechanical properties, the highest hardness is 99,5 HD at 10% Zn addition for all sintering temperatures. With the addition of Zn the mechanical properties is increasing.
