The influence of 425( ) mild steel particles (MSp) on the mechanical properties of structural AA6063 aluminum alloy has been studied. About 5 to 10 wt% of filler are added to molten structural aluminum alloy and cast using the stir casting method. The cast samples are homogenized at 470°C for 8hrs. Some of the homogenized samples are rolled at ambient temperature (30°C) with 30% thickness reduction. Half the rolled samples are further tempered at 250°C for 8hrs and air-cooled. All processed samples are subjected to tensile, hardness, impact and microstructural examinations. The tensile strength of 124MPa is achieved with 10wt% MSp in as-cast condition with a ductility of 3.65% while hardness of composite increases with filler content. The optimum composite strength and ductility is obtained at 15wt % of filler combined with rolling and tempering processes (11 0.4876MPa, 0.0482).
