In this study, used aluminum beverage cans were recycled and chemical composition of an aluminum alloy ingot obtained from the recycled cans was examined by emission spectroscopy. The ingots were remelted at 750 °C, and then 0.25 wt.% Si, 0.5 wt.% Si, 1.5 wt.% Mg and 3 wt.% Mg powders were added to improve the mechanical properties of the alloy. The microstructure and mechanical properties of the as-cast recycled aluminum alloy and recycled Al-Mg-Si alloy at different Si and Mg contents were investigated via optical microscopy (LOM), scanning electron microscopy (SEM), hardness tester, and universal testing machine (UTM). The results revealed that the microstructure of the recycled aluminum alloy ingot consisted of Al-Mg-Mn solid solution and four different secondary phases: Al 19 (Fe 3 SiMn), Al 33 (Fe 3 SiMn), Al 11 (Fe 2 Mn), and Al 19 (Mg 2 Si) phase. The hardness and tensile strength of the recycled aluminum alloy increased with the addition of Si and Mg powders. As the Mg content increased from 1.5 wt.% to 3 wt.%, the volume fraction of the Al 19 (Mg 2 Si) secondary phase increased. The experimental results indicated that the addition of Si and Mg can modify the microstructure and improve the mechanical properties of the recycled aluminum alloy. [ABSTRACT FROM AUTHOR]
