Abstract—Aluminium based Matrix Composites (AMCs) possess tremendous potential for number of applications in addition to their present uses in different engineering fields. In the present study, aluminium composite with 5% reinforcement of Al2O3 + fly-ash was prepared using a cost effective stir casting technique. Hardness tests carried on the composite using Rockwell hardness tester showed increase in hardness over the monolithic aluminum metal. Testing of wear behavior was done on pin on disc apparatus at a normal load of 40 N and sliding velocities of 0.8 m/sec and 1 m/sec. The fabricated composites showed improvement in wear resistance over the monolithic aluminum metal. Considering all the factors, it can be concluded that aluminium based composite with 5% Al2O3 + fly-ash reinforcement possess better mechanical and wear resistance properties than rival specimen, i.e., pure aluminium.
