Die casting is the main processing form of automotive aluminum alloy components.

    Die casting is the main processing form of automotive aluminum alloy components. The traditional automotive manufacturing process mainly includes four major processes: stamping, welding, painting, and final assembly. Stamping is the use of small and medium-sized presses and molds, commonly used for the formation of steel, and aluminum alloy components are usually cast by die casting. Die casting is a method of obtaining castings by loading metal into the mold cavity at high speed under high pressure, forming and solidifying under pressure.

The penetration rate of aluminum alloy in large components of new energy vehicles is rapidly increasing.

    The penetration rate of large components such as chassis, body, and suspension is rapidly increasing, and the aluminum consumption per vehicle is expected to reach around 250/300kg by 2025/2030. According to CME Group analysis, by 2025, the aluminum consumption of pure electric vehicles will reach 226.8kg, with a penetration rate of 50%. By 2030, the aluminum consumption will reach 283.5kg, with a penetration rate of 56%. This is mainly driven by the rapid increase in penetration rates of components such as chassis, suspension, wheels, and transmission systems. According to the roadmap of energy conservation and new energy vehicle technology in China, the specific goal for aluminum used in bicycles is to reach 250kg by 2025 and 350kg by 2030.
