The importance of reinforced particle with aluminium metal matrix is to study and predict in the enhancement of mechanical properties like tensile and tribological property. Metal matrix composites (MMCs) constitute an important class of design and weight-efficient structural materials that are encouraging every sphere of engineering applications. There has been an increasing interest in composites containing low density and low cost reinforcements. With the increasing demand of light-weight materials in the emerging industrial applications, fabrication of aluminum-boron carbide with graphite composites is required. In this context aluminum - boron carbide with graphite composites were fabricated by stir casting with different particulate composition of B4C (5%, 10%).Microstructure analysis was done with scanning electron microscope. With the increase the amount of the boron carbide, the density of the composites decreased whereas the hardness is increased. The ultimate compressive strength of the composites was increased with increase in the weight percentage of the boron carbide in the composites.
