Abstract: Aluminum alloy materials observed to be the best option with its one of a kind limit of outlining the material to give required properties. Aluminum alloy composites are increasing far reaching acknowledgment for aviation application in view of their high strength and density. In the present work, an endeavor is made to get ready and concentrate the mechanical properties of Aluminum LM13 – MgO particulates Composite. The Aluminum LM13– MgO particulates having 2wt%, 4wt%, 6wt%, 8wt% and 10wt% were manufactured by stir casting technique. The ingots were subjected to T6 Heat treatment to upgrade the properties. The composite samples were machined according to ASTM test benchmarks. The microstructures of the composites were concentrated to know the scattering of the MgO particulates in Matrix. It has been watched that expansion of MgO particulates essentially enhances extreme rigidity alongside compressive and hardness strength as contrasted and that of unreinforced composite.
