The ¾ of pure aluminium and ¼ of magnesium metal particles are fixed as a matrix and developed with different weight percentages of alumina (Al 2 O 3 ) and silicon carbide nanoparticles through liquid state electromagnetic stir cast process found good interfacial bonding was proved by scanning electron microscope (SEM) and X-ray diffraction (XRD) technique. Influences of electromagnetic stir action for Al 2 O 3 and SiC presence on hardness, tensile, and impact strength of developed composites are studied. Similarly, the composite's thermal adsorption behaviour was estimated using Differential-Thermo-Analysis (DTA) with a temperature span of 23ºC to 600ºC at a 24ºC/min heat rate. The composite consists of 9wt% Al 2 O 3 and 5wt% SiC and facilitates superior mechanical properties such as Vickers hardness, tensile and impact strength was 143.91 ± 0.92HV, 230.91 ± 1.10 MPa, and 11.98 ± 0.25 J respectively. The material loss of composite during thermal analysis was found to be negligible.
