Metal matrix composites are being increasingly identified in now a days as wear resistant material. This paper deals with the wear and hardness properties of the composite material Al-6061 alloy reinforced with Al2O3 and ZrO2 particulate and supported by stir casting method. The wear down rate and frictional properties of the composite were investigated with the help of pin and disk type of wear testing machine. The investigation was carried out with constant length of sliding distance and sliding velocity over different load ranges for aluminium metal matrix composite. The testing result indicated that the wear resistance increases when there is increase in the load. Additionally an effort was made by keeping Al2O3 as constant as 5% along with increase in 1, 1.5 and 2% of ZrO2. It was observed that, the strengthened aluminium metal matrix in addition of ZrO2 and Al2O3 decreases the range of wear rate. By using SEM the worn out surfaces were examined and it was observed that the micro cracks, mild and severe wear occurred in the composite worn surfaces and wear structure of the composite.
