Metal matrix composite (MMC) with improved thermal conductivity,abrasion resistance, tribology, creep resistance, dimensional stability,good stiffness-to-weight and strength-to-weight ratio will find application in the aerospace, automobile, mechatronics components (suchas sensor) and other engineering outfits. In the present work, the aim is to develop aluminum (AA1170) based silicon carbide particulate metal matrix composites with an objective to develop a conventional low-cost method of producing MMC's, and to obtain homogenous dispersion of silicon carbide. To achieve these objectives two stepmixingmethods of stir casting technique has been used. AA1170 and SiC (3, 9, 29 and 45 μm grit sizes) have been chosen as matrix and reinforcement materials respectively. Experiments have been conducted by varying weight fraction of SiC (2.5, 5.0, 7.5 and 10%). The results indicated that the stir casting method is quite successful in obtaining uniform dispersion of reinforcement in the matrix.Measured properties of aluminium silicon carbide (composite) showed increase in young's modulus (E) and hardness above the unreinforced aluminium, however, there was marginal reduction of electrical conductivity in the composite
