Because of large industrial development which the world has seen in all fields. scientists and researchers aim to produce new materials that having special engineering properties with low economic cost as fit multiple industrial application and uses. So in This present article We try to prepare composite materials based on aluminum alloy (6663) and reinforcement it by different particles having size of micron of Alumina and silicon carbide particles are added in specific weight parentage by stir casting technique to obtain Aluminum Which having the improving mechanical properties
