Aluminium matrix composites (AMCs) are the emerging and competent materials for numerous structural applications owing to their virtuous mechanical and physical characteristics. The inclusion of reinforcements into the metallic matrix enhances the specific strength, stiffness, hardness, creep, wear and fatigue properties related to general materials used for engineering applications. In this research work an attempt has been made to examine the fundamental mechanical properties of Al6063 hybrid metal matrix composite with two different fillers such as Al₂O₃ and Bamboo stem ash (BSA) as reinforcements by means of stir casting route. The mechanical properties of the resultant composites are observed as per ASTM standards and microstructural study is used to characterize the distribution of reinforcements. The result reveals that there is an enhancement in mechanical properties of the resultant composite material by the inclusion of Al₂O₃ and BSA reinforcements, this in turn recommend that this Al6063 composite has a substantial potential in various engineering applications as compared to pure Al6063.
