SiC particle-reinforced aluminum matrix composites have high specific strength, high specific modulus, high wear resistance, and excellent corrosion resistance, which are one of the best materials for replacing traditional steel due to the lightweight design they offer in mechanical structures. They have broad application prospects in the automotive, machinery, aviation, and electronic packaging fields. Therefore, they have received much attention from scientific research workers in all fields. This research summarized the fabrication technology, properties, and reinforcement mechanisms of SiC particle-reinforced aluminum matrix composites, and discussed the technical difficulties and improvements in the preparation of these composites. Finally, the research and applications of SiC particle-reinforced aluminum composites were summarized.
