Abstract: With industries like automotive and aerospace also being more inclined on the lightweight material and strength that is much substantial, the aluminium-based metal matrix composite has become a major focus of interest. This paper examines the influence of addition of tungsten carbide (WC) and magnesium (Mg) particles on the mechanical characteristics of Al6063 aluminium alloy. The crucible casting technique was made in two composite compositions 2.5 percent and 5 percent WC with a fixed 1 percent Mg(percent weight). The tested fabricated composites were tested on hardness, tensile strength, compressive strength, and impact energy. The findings of this study show that as the WC content is increased, there is a significant increase in hardness and strength with the 5 percent WC 1 percent Mg composite having the best mechanical performance. Nevertheless, the impact performance of the unreinforced Al6063 alloy was better probably because it is more readily ductile and all particles were not agglomerated. This was further substantiated by scanning electron microscopy (SEM) analysis which demonstrated a homogenous distribution of the reinforcement particles and a fine grain structure. On balance, it can be concluded that the created composites have high prospects of use in lightweight structure products that need increased mechanical strength.
