Copper (Cu) metal matrix composites have gained significant attention due to their potential for usage in numerous applications, including aerospace, automotive, and electrical industries. These composites possess a unique combination of properties of their elements that are superior to those of pure copper. By modifying the amount and type of reinforcement particles used to alter the highly dependent microstructure, the properties can be controlled and managed. Copper has been reinforced with different kinds of nano-particles, including oxides, nitrides, carbides, carbon nanotubes, and other hybrid reinforcements, which can enhance wear resistance, damping characteristics, and the mechanical strength of the underlying material. However, due to the low wettability of these particles, conventional casting techniques are not suitable for preparing nano-composites. Numerous alternative methods have been explored and studied in the literature to fabricate copper metal matrix nano-composites. This comprehensive analysis aims to review the key manufacturing methods employed for the synthesis of copper-based nano-composites and their potential primary applications, with a focus on the synthesis and characteristics of this novel class of materials.
