AbstractThis study is concerned with investment of the commercial purity aluminum scrap (1100) by converting it to aluminum matrix composite reinforced by iron oxides particles. The particle size, X-RD and microstructure of the oxides particles were found. The weight ratio of added oxides was (1%, 1.5% & 2%) .Wettabilty was improved by pure magnesium additive. Electric mixer is used to dispersing iron oxides particles in the aluminum scrap molten. After that, was cut the composite to samples and prepared these to tests such as; tensile strength, compression strength, hardness, wear resistance, impact strength (toughness), corrosion resistance and microstructure. From tests above found that; tensile strength, compression strength, wear resistance, hardness were increased in composite compared to the base metal , while impact strength (toughness)and corrosion resistance were lowered slightly in composite compared to the base metal .In wear resistance test used (pin-on-disk) technique where load ,sliding velocity and sliding distance were constant. The microstructures were taken for base metal and composite before and after corrosion to comparison. .
