The rapid rise of new energy vehicles under the“dual carbon” goals has shifted the focus of vehicle lightweighting from traditional structural and process innovations to the substitution and optimization of materials. Aluminum alloy materials highly match the requirements for materials used in automotive lightweighting, and are currently the most preferred materials. This paper reviews and discusses the research and development, application and new directions of aluminum alloy materials in automobile lightweighting.Firstly, the paper introduces the main brands and the application status of die casting aluminum, which accounts for more than 70% of the aluminum used in automobile drive systems, chassis systems and body structure parts. The focus is placed on analyzing the research status of integrated die casting technology and its necessary non-heat treatment aluminum alloy. The paper summarizes the use of wrought aluminum alloy in the automotive field, including the stamped parts, profiled components and forgings. It also discusses the research status of traditional automotive forged aluminum and high-strength aluminum, guided by the development trend towards high-strength and ductile aluminum alloys. Finally, the existing bottlenecks of aluminum alloy materials in the automotive field are analyzed and prospected.
