This paper deals with the value of composites as engineering materials which is shown by the researchers. The composite is one of the most important and popular material is available in the market. The reinforcement of one or more metals with base material leads to an improvement in its properties of base metal. Many researchers are doing lot many combination for getting the best quality of composite in the form of MMC. In order to overcome the barriers of conventional materials the MMCs plays an important role, in applications like automobile industries, aerospace, defence and thermal management systems.The required properties of material for any special application we can produce or created by the help of Metal Matrix Composite. The use of MMCs in various applications have been increased due to availability of these materials at lower cost. In order to exploit needful physical and mechanical properties Al is reinforcement with different materials. The literature review with respect to current aspect of study in Metal Matrix Composite the base metal is Aluminium 6061 has maximum applications which is reinforced byzircon, Alumina, red mud,silicon carbide,fly ash and boron carbideetc. The reinforcement of material is depend on the needful Mechanical and tribological properties. These properties can be enhanced with the use of reinforced material of suitable size and composition.The detailed discussion of those properties are given in this article.
