This review paper represent the fabrication procedure of making aluminium magnesium composite material by use powder moddulory method.in this method we make this composite materil by doing recinforcement process.composite material is less in weight,high in strength,or also less coastly.composites have many different properties like high thermal conductivity,haigh tensile strength.composite material is generally an mixture of two or more same or different metlas.we can use composite metal in different mechanical sector,because of there multipurpose uses. In composite material we can easily find two metlas properties in one metal. . The new material may be preferred for many reasons. Composite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, race car bodies, shower stalls, bathtubs, storage tanks, imitation granite and culture marble sinks and countertops. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments. Surface metal matrix composites (MMCs) are a group of modern engineered materials where the surface of the material is modified by dispersing secondary phase in the form of particles or fibers and the core of the material experience no change in chemical composition and structure.
