dc.description.abstract	Metal matrix composites are undoubtedly a group of advanced engineering materials. Compared to unreinforced matrix material, they are characterized by increase strength, greater stiffness, increase wear resistance, better mechanical properties and dimensional stability at elevated temperatures as well as lower density. This paper deals with the mechanical properties of recycled GGG-40 cast iron chips reinforced AlMg1SiCu aluminum chip composites. Thus, composition type is aluminum metal matrix composites (AMMC) is fabricated by stir casting method. The composites were fabricated with various volume percentage levels as aluminum reinforced with (0, 5, 10 &15%) of GGG-40 cast iron chips. Fabricated composites specimens were prepared according to ASTM standard size to study. The improvement of GGG-40 cast iron chips reinforcement on mechanical properties of aluminum alloy composites were analyzed in this study. The microstructure studies were also carried out. It is observed that increasing the GGG-40 cast iron chips content within the aluminum matrix results in significant increasing in ductility, hardness, ultimate tensile strength up to 10% reinforcements. The addition of GGG-40 cast iron chips greater than 10% conversely decreased the hardness, ultimate tensile strength of the composites and porosity increased due to density difference between the composite. Key words: AlMg1SiCu aluminum alloy, GGG-40 cast iron, reinforcement, metal matrix material.	en_US
