Aluminum Metal Matrix Composites (AMMC) the most useful and high-tech composites aluminum (Al) as the best metal for producing these composites. Linking Aluminum and Zirconium dioxide (ZrO2) will conceive a matrix with the super corrosive resistance and mechanical properties like strength at elevated temperatures. Also, the abrasive wear of these matrixes will be revised. In the current research, a review on aluminum/ zirconium dioxide composites has been performed. This endeavor approaches the first fabrication and characterization of AMMCs based on Zirconium dioxide (ZrO2) ceramics for bettering the mechanical and wear properties due to the higher strength and hardness. Microstructures of these composites in powder metallurgy conditions show different size distribution of zirconia with different proportions in the composite. Also, there is a case-study about density and compressive strength and hardness of aluminum/ zirconia composites. The green specimens prepared by stir casting technique with different zirconia percentages (5, 10, 15), in a tubular muffle furnace at temperature of 9500c using nitrogen gas shielding environment. These specimens were further investigated by different physical and mechanical examining methods to observe which conditions are the best to obtain desired properties. The most effective tensile and compression strength was obtained with the specimen including 10% of zirconium dioxide sintered.
