In current scenario Metal Matrix Composites (MMCs) are increasingly becoming a new class of material in aerospace, automobile applications. Since their properties can be tailored through the addition of selected reinforcements, superior strength to weight ratio, wear and high temperature resistance. Aluminum alloy-based metal matrix composites (AMMCs) have been widely utilized in most of the industries and engineering sectors in present time. The current research work focuses on experimental investigation of aluminum 6061 metal matrix composite material. Four types of impurities are considered in the study namely, graphite, chromium, nickel and magnesium. The fabrication process is carried out using stir casting process with the required temperature and conditions. The results showed that sample having the composition wt % of graphite 3%, Mg1%,Ni 2% and Cr 2% has the best most optimummechanical properties compared to base materialAl6061. Mechanical properties like tensile strength Impact and hardness, which were observed from the prepared specimens in theexperiment.
