In this study, A2014 alloys were reinforced with varied percentage of Alumina by liquid metallurgy route using permanent moulds. They were Heat treated (T6) and tested for microstructure, mechanical properties and wear behaviour. The wear tests were conducted using Pin-on-Disc apparatus at a constant sliding velocity of 1m/s and wear load of 30 N. Microstructure revealed uniform distribution of reinforcement in the matrix resulting in improved mechanical properties and wear resistance compared to un-reinforced material. This improvement in mechanical properties and wear resistance may be attributed to improved bonding of reinforcement in the matrix. Improved Mechanical Properties, Wear resistance were observed for Heat treated A2014 and its Composites
