Application of aluminum alloy in new energy vehicles

Due to the impact of battery weight and battery mileage on new energy vehicles, weight reduction is more urgent than traditional vehicles. Among automotive lightweight materials, the comprehensive cost performance of aluminum alloy materials is higher than that of steel, magnesium, plastics and composite materials, regardless of application technology or Both operational safety and recycling have comparative advantages.

 The aluminum components used in new energy vehicles mainly include body, wheel hub, chassis, anti-collision beam, floor, power battery and seat. The body includes the body frame made of high-performance aluminum profiles and the skin and doors made of high-precision aluminum plates; aluminum alloy wheels; chassis includes high-strength large-section aluminum profile structural parts and aluminum alloy forgings ; Anti-collision beam bumpers made of profiles; new energy bus floors; lithium-ion batteries and aluminum-ion batteries. Lithium-ion batteries include battery positive aluminum foil, battery aluminum shell and battery aluminum tray; new energy bus seat systems, etc.

The application of aluminum alloy materials in new energy vehicles varies depending on the concept of different car companies and different model designs. New energy vehicles with all-aluminum bodies will use a large amount, while other new energy vehicles will use relatively less. Some cars purchase aluminum parts and process their own parts, while some car companies purchase aluminum finished parts and then assemble them directly on the line.
