In this study, effects of aging on the mechanical properties of Al-Si alloy that containing 0.20 wt. % and 0.40 wt. % Mg were investigated. All alloys were homogenized at 550oC for 12 hours. The solution heat treatment of the alloy was carried out at 525oC for 3 hours and then samples were water-quenched. The specimens were artificially aged at 180oC for three different time durations. The structural, morphological and mechanical properties of the specimens were examined by using scanning electron microscope (SEM), X-Ray diffraction (XRD), and compression, notched impact, wear and hardness tests. it was determined that the values of hardness, yield and ultimate strengths increased but the ductility of the alloy decreased with aging time for both alloys. The wear resistance of 0.40 wt. % Mg containing alloy was higher than that of 0.20 wt. % Mg containing alloy. It was observed that increasing Mg ratio resulted in higher hardness, yield and ultimate strengths and impact toughness.
