Aluminium (Al) matrix composites are advanced engineering materials consisting of one or more reinforcements, usually ceramic or metal. Aluminium matrix composites combine the properties of aluminium such as high strength, low density, high corrosion and wear resistance with the superior properties of reinforcing materials, resulting in higher performance materials. Aluminium matrix composites offer advantages such as light weight due to their low density, high strength and good corrosion resistance, and are preferred in a wide range of structural applications in the automotive industry, aerospace industry, defence industry and construction and architecture sector. In the production of aluminium matrix composites, Powder Metallurgy technique is the most effective method that stands out by providing homogeneous distribution of reinforcing materials, which are of great importance in the composite structure, superior performance of the composite material and energy saving due to the production using less energy and material saving due to the need for only as much material as the sample to be produced. In this study, Al matrix composites were produced by powder metallurgy technique by reinforcing graphene and magnesium chips at increasing ratios by wt. %. Firstly, the matrix and reinforcement powders were ground by Mechanical Alloying method, the composite powders produced were sintered by hot pressing method and the microstructure of the composites produced were carried out, tensile strength values and hardness values were measured. Accordingly, in the microstructure examinations of Al matrix composite materials with increasing graphene and Mg ratios, it was observed that the agglomeration in the structure increased with increasing reinforcement amount and the hardness values of the composites produced were determined as 45 HB, 33.5 HB, 25 HB and 23 HB, and the tensile strength values were measured as 53 MPa, 49 MPa, 34.6 MPa and 29.3 MPa, respectively, according to increasing reinforcement ratios.
