Aerospace and automotive industries rely heavily on aluminium alloys because of their advantageous physical and mechanical properties. This paper presents studies on the performance of stir cast B4C (Boron carbide) and Gr (graphite) reinforced aluminium metal matrix composite (AMMC). Particulate reinforcement of B4C and Gr is in the ratio 2:1 (wt.%). Characterization of AMMC's mechanical properties reveals that the composite has enhanced mechanical properties compared to Al2618. Through Scanning electron microscope(SEM), it is identified that microstructure of AMMC and distribution of B4C and Gr particles in Al2618 are found to be uniform. Based on the results of the experiments, it was determined that the best AMMC mixture for improving the material's mechanical properties is a combination of B4C and Gr, with the proportions at 8:4. As a result, the automobile sector stands to benefit greatly from the use of this AMMC in the production of engine components.
