Magnesium based metal matrix composites (MMCs) offer potential for advanced structural applications with high specific strength and modulus, as well as good elevated temperature resistance along with light weight and for marine applications. The Magnesium and its alloys have excellent ductility but reasonable strength makes it widely used in the field of automotive, aerospace. The reinforcements added to MMC will improve the properties of the composite like shear strength, tensile strength, hardness, and wear behavior. Discontinuously reinforced magnesium matrix composites are fast emerging as engineering materials and competing with common metals and alloys. They are gaining significant acceptance because of higher specific strength, specific modulus and good wear resistance as compared to ordinary unreinforced alloys. The microstructural characteristics studied in order to comprehend the mechanical response showed significant grain refinement due to grain boundary pinning effect of nano-Al2O3particles which resulted in strengthening of Mg. In the present work, magnesium Alumina composite developed using a stir casting technique is studied for Tensile strength, Shear strength and change in percentage of elongation by using the universal testing machine and torsion testing machine. The Tensile strength and shear strength of the composites are investigated at room conditions by varying percentage of alumina nanoparticles by weight 2% to 8% with increment of 2%.
