A composite combines two or more different materials to create a superior or unique material, a broad definition that applies to all composites. However, the term “composite” more recently refers to reinforced plastics. Aluminum MMCs are known for their lightweight, high strength, and excellent corrosion resistance, providing a sustainable alternative to traditional metals in high-performance environments. These composites offer superior strength-to-weight ratios, enhanced wear resistance, and improved thermal stability, making them ideal for aerospace, automotive, and defense applications. The manufacturing methods, such as powder metallurgy, casting, and stir casting, play a crucial role in determining the composite's properties. This review paper focuses on composites, specifically the production technology of metal matrix composites (MMCs), with a focus on stir casting. It discusses various manufacturing processes for MMCs, such as injection molding, friction stir processing, mechanical alloying, squeeze casting, and continuous binder powder coating. Additionally, the paper examines microstructural analysis, tensile testing, hardness testing, and wear testing, highlighting how the matrix and reinforcement phases influence these properties.
