In this present work an effort has been made to fabricate and study the properties of magnesium metal matrix composites. The specimens were fabricated using centrifugal casting technique. Nowadays, the growing interest in developing Magnesium (Mg) towards the development of advanced material. Although corrosion is a concern for Mg, other physical properties, such as low density and young’s modulus, combined with good compatibility, lead to significant research and development in this area. Nowadays Titanium based matrix was used for automobile applications from past decade. But the effective non- infected magnesium matrix is going to be developed for the replacement of Titanium matrix due to low cost, low density, mechanical and chemical characteristics. Centrifugal casting has the advantages of being able to make uniform work pieces but the disadvantages equipment and maintenance costs are expensive. The aims of this study were to compare the tensile strength and hardness of the centrifugal casting method. The material used in this study is Mg with TiB2, Al2O3 reinforced composite. Tensile test procedure using ASTM-E8 standard and hardness test procedure using ASTM-E92. The results showed that the highest tensile strength in the Mg 94% + 2% TiB2 + 4% Al2O3 centrifugal casting is 82 MPa. The hardness test was carried out to find out the hardness of the cast composites using micro hardness testing machine. The hardness test and its results show that the hardness value of Mg 92% + 2% TiB2 + 6% Al2O3 composite is higher than other reinforcements. Morphology of the different composition cast composites reinforced with TiB2, Al2O3 were studied in detail by optical microscopy to analyze particle distribution in the magnesium metal phase.
