Aluminum matrix composites reinforced with Nano-sized particles are widely used for high performance applications such as automotive, military and aerospace industries because of their improved physical and mechanical properties. In the present research, Aluminium Alloy (Al7075) matrix was reinforced with Aluminium Oxide Nanoparticles in the weight % of 0.1%, 0.2%, and 0.3%. The process was carried out by stir casting method at a temperature of 800 ᵒC. The Nanocomposites were tested under SEM for structural characterization. These Nanocomposites were further investigated in order to identify the behavior of mechanical properties. The results revealed that properties such as density, hardness and tensile strength increased with increase in reinforcement percentage.
