The purpose of this research is to examine Al/Cu/Mg metal composites in terms of their mechanical properties and microstructural features. Powder metallurgy was used in conjunction with casting to create the composites. Mechanical characteristics were determined by subjecting the samples to hardness, tensile, and compression tests, while scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to analyse the samples' microstructure. Incorporating Mg and Cu into the Al matrix significantly enhanced the composites' strength and ductility, as the results demonstrated. The scanning electron microscope and X-ray diffraction analyses both showed that the reinforcement particles were uniformly dispersed throughout the matrix. Microstructural and mechanical characteristics, as well as possible applications in the aerospace and automotive sectors, are examined, and conclusions are drawn on the manufacture and characterization of Al/Cu/Mg metal composites with weight percentages of 4%, 8%, 12%, and 16%.
