In this paper we prepared a hybrid composite and investigation has been done on its mechanical behaviour. The best alternative material is Aluminium alloy found to with its distinctive capacity of crafting the materials to give prerequisite properties are gaining wide spread acceptance for Various industries like automobile, industrial, and aerospace are accepting the Aluminium alloy Metal Matrix Composites (MMCs) because of their low density, high strength and good structural rigidity. In the current work, an effort is made to formulate and relate the mechanical properties of Al6061-SiC/Graphite hybrid composites. The Metal matrix composites were fabricated using stir casting technique in which amount of reinforcement is varied from as 15% of the total weight. The set composites are described by micro structural studies and mechanical properties were assessed as per the standards. The micro photographs of the composites revealed legitimately even dispersal of the particles in composites with huddling at few places. The spread Graphite and SiC in Al6061 alloy subsidized in augmenting the tensile strength and hardness of the composites. The scanning electroencephalographs of the samples indicated uniform distribution of the reinforcement particles in the matrix without any voids.
