An attempt has been made to fabricate and compare the properties of aluminium hybrid metal matrix composites in this current work. Two specimens were fabricated by adding 10% (wt) of each Al2O3 and SiC along with 1% (wt) Graphite to AA6351. The stir casting route with bottom pouring technique has been employed to fabricate the two specimens. Morphology of the cast composites reinforced with Al2O3/Gr and SiC/Gr were studied in detail by optical microscopy to analyze particle distribution in the aluminium metal phase. The hardness test is carried out to find out the hardness of the cast composites and parent metal using Vickers micro hardness testing machine. Mechanical testing is carried out on the tensile samples prepared from the two cast composite specimens and parent metal specimen. Wear test is carried out to study the wear resistance behaviour of cast composites and parent metal specimen. The hardness, tensile strength and wear rate of the two HMMCs are compared with the parent metal specimen and the better HMMC is determined based on the comparison of test results.
