The objective of current paper is to investigate mechanical, and tribological behavior of Al7150 matrix reinforced by Boron Carbide. Stir casting process, was used to make Al7150-Boron Carbide Metal Matrix Composites (MMCs). The incorporation of reinforcement in matrix ranged from 0 to 2 wt%, with 0.5 intervals. The collected composite samples were used in research studies including physical, mechanical and tribological experiments. The experiments were carried-out in harmony with ASTM Standards on Al7150 alloy & its composites. The test results show that as the reinforcing percentage increased, characteristics like hardness and tensile strength increase, while density decreases. The wear experiment was carried out using a tribometer with pin-on-disc setup, and obtained results show that composite possess a higher wear resistance.
