Aluminium Matrix composites (AMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence, engineering and other industries. AMCs are projected to significantly reduce the overall weight of the vehicles and aircraft while maintaining satisfactory structural strength. Reinforcement of nano-sized range particles with aluminium matrix yields improved mechanical and physical properties in composite materials. The distribution of nano sized reinforcing particles also changes morphology and interfacial characteristics of nano composites. In this study pure aluminium and nano Al2O3 composites have been developed by using stir casting method. Different weight % of Al2O3 nano particles (from 0 to 12 % with step size of 3 %) were used for the analysis of composites. Microstructural study of the composites were characterized with the help of scanning electron microscopy (SEM) and it is found that nano particles (Al2O3) in aluminium metal matrix is distributed uniformly with agglomeration at some place. Various mechanical properties of composites like tensile strength, compressive strength, and hardness were measured. Results revealed that the tensile strength, compressive strength and hardness of composites increases with increase the weight % of Al2O3 particles. However the ductility of composite with nano Al2O3 particles reduced with increasing the weight % of Al2O3 particles
