Research Status of Lightweight Materials and Manufacturing Processes in Automobiles

Since the beginning of the 21st century, China's automobile market has shown a rapid development trend. To meet the domestic demand for the development of the automobile industry and provide convenience for transportation, automobile manufacturers have made long-term innovations, explorations, theoretical verifications, and designed more advanced and reasonable automobile materials and manufacturing processes, gradually moving towards lightweighting and adopting more advanced manufacturing processes. This paper conducts a comprehensive and detailed analysis and discussion on the application status of lightweight materials in automobiles and assembly processes, fully understanding the advantages and characteristics of new materials such as aluminum alloys, high-strength steels, and composite materials. Predictive analysis of the development prospects of the automobile industry is of particular importance.
