The extensive application of aluminum alloy materials in the automotive industry primarily aims to reduce vehicle weight and fuel consumption while enhancing load capacity. Its excellent corrosion resistance and formability make it the ideal choice. It is commonly used to manufacture battery trays and casings, where its good sealing properties during welding improve the safety and durability of battery packs. In the manufacture of body structures such as frames and chassis, it reduces the use of rivets, lowers weight, and enhances structural strength and fatigue performance. It is also used to make motor casings and brackets, where welding high-strength aluminum alloys results in minimal deformation, improving structural integrity and heat dissipation. In thermal management systems, it is used to manufacture radiators and cooling plates, ensuring sealing and enhancing the efficiency and reliability of the thermal management system. Additionally, it is used in the production of charging equipment like charging piles and interfaces, where high welding quality meets the strength and durability requirements of charging devices.
