Abstract: The applications of the composite material have grown steadily and which occupy the new market. The main reason for using the composite is to reduce the weight. Aluminium has a wide advantage in research field which is used as base metal in many MMC’s. In this experimental study, Aluminium graphite MMCs was fabricated by mixing of graphite powder into aluminium powder followed by powder metallurgy route . The composite were compacted and sintering was done at 450°C. It has been found that addition of graphite into aluminium does not result in much improvement in hardness due to the soft nature of graphite.
