Abstrakt: Aluminum alloys are a crucial material due to their high resistance to corrosion and strength to weight ratio, particularly in pressure systems and transport applications. However, they have low melting temperatures and are relatively soft compared to other engineering materials. Utilising secondary reinforcing components such as tungsten carbide, fly ash, mica, boron carbide, silicon carbide, graphite, e-glass, and aluminium oxide, researchers have recently concentrated on creating metal matrix composites. Stir casting was used to create aluminium alloys with different weight percentages of magnesium and zinc. The alloys were then re-aged at 150 °C for different holding times. SEM image of a worn-out surface reveals material flow, scratches, and narrow grooves that are caused by wear parameters including applied stress, sliding velocity, and sliding distance. Only 5.57% more ultimate tensile strength was achieved for the highest weight percentage of magnesium and zinc after 7 h of ageing. Improved mechanical qualities were seen in SEM pictures, and regression analysis confirmed the experimental findings.
