The conventional monolithic materials have limitations in achieving good combination of strength, stiffness, toughness and density. Aluminium alloy based metal -matrix composites (MMCs) possess significantly improved properties including high specific strength, specific modulus, damping capacity and good wear resistance compared to the unreinforced alloys. Generally aluminium alloy with silicon carbide have high tensile strength, boron carbide with aluminium alloy increases the hardness of the composite material. This experimental investigation is aimed to increase the tensile strength and hardness of aluminium alloy 6082- T6 with silicon carbide and boron carbide. The stir casting method is used for mixing the silicon carbide and boron carbide with aluminium alloy 6082 - T6 composite material. The tensile strength values of Aluminium Alloy 6082- T6 with silicon carbide and boron carbide are compared with Aluminium Alloy 6082- T6 composite material.
