What aluminum alloys are used in electric vehicle battery boxes?

Electric vehicle (EV) battery boxes are traditionally made of aluminum and steel.Aluminum is the most common material used for battery cases because it’s lightweight and provides structural rigidity.

The battery boxes material is a high-purity aluminum alloy product formed through processes such as hot rolling, cold rolling, annealing, stretch bending and straightening, and aluminum foil rolling. It is used to hold the electrolyte and plate set. This kind of shell must not only be acid-resistant, heat-resistant, and shock-resistant, but also must have high strength and a thin shell wall.

Aluminum plates for battery boxes mainly include 3xxx series, 5xxx series and 6XXX series aluminum sheet coil.Among them, 3003 aluminum plate is usually used for power battery shell materials and battery water-cooling plates; 5083 aluminum plate is used for battery side plates; 5182 aluminum plate is used for battery covers; 6061 aluminum plate is used for power battery trays, etc.
