Research Status of Lightweight Materials and Manufacturing Processes in Automobiles

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