Metal Matrix Composites (MMCs) have increased use in current applications because of their better strength-to-weight ratio and high temperature resistant behavior etc. They impart the combined benefits of metals and ceramics. For the construction of Aluminium MMCs using the stir casting technique, pure Aluminum was used as the matrix, and SiC and Flyash were chosen as reinforcement materials, respectively. Mechanical tests were carried out after the manufacture of MMC samples by altering the weight fractions of SiC and Flyash (5-25%) while keeping all other parameters constant. The maximum hardness value was obtained in the case of Al +21 percent SiC, while the least value was obtained in the case of Al +7 percent SiC. Impact strength improves as percent Wt reinforcements increase, and compression test results show the similar trend.
