The effect of micro-alloying Sn (0.08 wt.%) on dry sliding abrasive wear behaviour of cast Al-Mg-Si alloy was investigated. Additionally, microstructure, hardness, and their impact on wear resistance were also investigated. It was observed that Sn contributes to the hardness and accelerates the age-hardening response ofthe Al-Mg-Si alloy. Sn addition also favours the formation of script-like Al(Fe, Mn)Si phase and increases the amount of Mg2Si precipitate. SEM investigation of worn surfaces reveals a similar abrasive wear mechanism in both the alloys which were micro-cracking, ploughing, and delamination. The study also reveals that improving the hardness by micro-alloying 0.08 wt.% Sn can prevent mass loss and marginally improves the wear resistance of the Al-Mg-Si.
