AA6082/B4C and AA6082/SiC were prepared via stir casting accompanied by an inert-gas to prevent oxidation. The samples for both the composites were produced with varying wt% of 0, 5, 10, 15 and 20 of B4C and SiC for their respective composites. This work gives emphasis on the comparative measurements of hardness, tensile strength, percentage elongation, Impact strength, density and porosity of the AA6082/B4C and AA6082/SiC composites. The microstructural was studied using X-ray diffractometer and SEM. The micro hardness in AA6082/B4C composites increases to 15.8% and the increase in AA6082/SiC composites is 11.9% only when compared with the base alloy whereas the increase in ultimate tensile strength for B4C and SiC reinforced composites was reported to be 31% and 19.1% respectively. At 20 wt% of B4C, hardness and tensile strength of AA6082/B4C composite tends to decrease due to the development of clusters and increased porosity. The transformation in the nature of material from ductile to brittle decreases the impact strength and the resistance in the flow ability presented by the hard ceramic particles lowers down the percentage elongation. Density reduces from 2.67 g/cm3 in base alloy to 2.48 g/cm3 in AA6082/B4C and 2.56 g/cm3 in AA6082/SiC composites respectively. The formation of voids in AA6082/SiC composites makes it less porous then AA6082/B4C composites and this was because of the more agglomeration in SiC composites due to their high density.
