Aluminium metal matrix composites are gaining widespread acceptance for automobile, aerospace, agriculture farm machinery, defence sector and many other industrial applications because of their essential properties such as high strength, low density, good wear resistance, ease of production and adaptability to modification compared to any other metal. The present study deals with the addition of reinforcements such as fly ash, silicon carbide to the Aluminium matrix in various proportions. Each reinforced material has an individual property which when added improves the properties of the base alloy. An effort has been made to review the different combinations of the composites and how they affect the properties of the different alloys of aluminium. Comprehensive knowledge of the properties is provided in order to have an overall study of the composites and the best results can be employed for the further development of the Aluminium reinforced composed. The investigation shows that Al metal matrix composites can be replaced with other conventional metals for better performance and longer life
