Structural applications of aluminium have grown considerably in the last decades. This paper reviews research on patents of aluminium composites synthesized methods, such as mechanical alloying, hot pressing, sintering, selfpropagating high-temperature synthesis, and spark plasma sintering. It seems apparent from the foregoing overview that aluminum alloys possess a number of very attractive characteristics which, together with their very light weight, make then extremely attractive for many applications. Further, their versatility with respect to options of how to shape them and strengthen them provide an amazing variety of choices when you are looking for an ideal material for a special application. At the same time, a further study for optimizing the processing technologies is required to improve the property of Aluminium composites. Future directions in this field have been suggested.
