Metal matrix composites are of great interest in industrial applications for its light weight with high specific strength, stiffness and heat resistance. The processing of MMCs by stir casting process is an effective way of manufacturing. In this paper the comparison of mechanical properties of Aluminium 7075 as a base metal and varying composition of fly ash by 3 and 6 wt.% SiC and 7% fly ash as reinforcement is carried out. Scanning electron microscope was used to confirm the presence of SiC and fly ash. The composites with 6% SiC was found to have maximum hardness whereas composites of 6% and 5 % fly ash were found to have minimum hardness. The mechanical properties such as wear resistance were studied. From the results, it has been finalized that the addition of 6% SiC was identified to show the least wear rate.
