In recent years, with the rapid development of the automotive industry, cars have gradually been heading towards lightweight structures. Currently, the application of various lightweight metal materials, including aluminum alloys, is becoming increasingly widespread. Aluminum alloys, as a new type of lightweight material for cars, can significantly reduce the weight of vehicles, improve their fuel efficiency, and can be recycled, meeting the energy-saving and environmental protection requirements in our country. Lightweighting is an inevitable trend in the current automotive industry and a major driving force for achieving "dual carbon" goals. With advancements in high-strength lightweight alloy forming and processing technologies, aluminum alloys will have even better processing techniques for automotive lightweighting, and their demand and development prospects for lightweighting will be broader. This paper will focus on aluminum alloy materials required for future automotive lightweighting.
