Composites are a class of materials that give the desired individual tribological and mechanical characteristics. In composite materials, more than two materials are combined to provide a unique combination of properties. This article describes the tribological and mechanical properties of Al6061 reinforced with Al2O3, found experimentally. This article describes the preparation of Al6061 composites with 5 % Al2O3 (size 50 microns) by stir casting process. The hardness of Al6061 with and without amplification was found out with the help of Rockwell hardness tester for 10 seconds at a load of 100 kg. It was found that the hardness of Al2O3 reinforced Al6061 increases compared to unreinforced Al6061. The characteristics related to wear of Al6061 and the new composite material Al6061+Al2O3 were studied. The “pin on disk” method was used with the variation of load varying from 5N-200N and a speed range of 200-1500. An analysis of the sensitivity of key parameters such as load and speed is also described. The results show that the newly developed composite material has a lesser specific rate of wear.
