Battery aluminum tray, aluminum for new energy vehicles

Aluminum alloys are widely used in new energy vehicles, and battery aluminum tray is a typical aluminum for new energy vehicles. aluminum alloys can be used for structural parts and components such as body, engine, and wheels. Aluminum alloys for vehicles mainly include 5××× series (Al-Mg series), 6××× series (Al-Mg-Si series) and so on. It is understood that the battery aluminum trays are mainly made of 3××× and 6××× series aluminum alloys. In the context of energy conservation and environmental protection needs and the advancement of aluminum alloy technology, the amount of aluminum alloys used in automobiles is increasing year by year. According to relevant data, the average aluminum used in European cars has tripled since 1990, from 50KG to the current 151KG, and will increase to 196KG in 2025.

New energy vehicle aluminum sheets are different from traditional vehicles. New energy vehicles use batteries as power to drive the vehicle. The battery tray is the battery unit. The module is fixed on the metal casing in the most favorable way for thermal management, and plays a key role in protecting the normal and safe operation of the battery. Its weight also directly affects Vehicle load distribution and endurance of electric vehicles. Among them, the body includes a body frame made of high-performance aluminum profiles and skins and doors made of high-precision aluminum sheets; aluminum alloy wheels (cast aluminum wheels or forged aluminum wheels); chassis includes high-strength section aluminum structure parts and aluminum alloys Forgings: In the past, new energy vehicles mostly used steel materials to make electric vehicle power battery trays, but now the application of aluminum alloy materials has gradually surpassed that of steel materials. Aluminum alloys have obvious advantages in terms of density, compression and welding lights.
