3003 aluminum sheet alloy is preferred for power battery shell materials. To know which material is better for the power battery shell, first we should know what the power battery is. The global electric vehicle industry has basically agreed that the battery that provides the driving force for electric vehicles is called a power battery, including traditional lead-acid batteries, nickel-metal hydride batteries and emerging lithium-ion power batteries. Now the world is currently advocating automotive lightweight, aluminum is the best choice.

3003 aluminium has good formability, mainly used in deep-drawn materials, using 3003 aluminum alloy products for stamping parts, models, shells. 3003 aluminium sheet as power battery shell material is one of the superior products. It has mature technology, excellent quality and global distribution. 3003 aluminum sheet coil has the following 4 points performance:
1, Excellent forming processing characteristics, high corrosion resistance, good weldability and electrical conductivity.
2, smooth surface, good plasticity, pressure resistance.
3, with impact resistance, not easy to break and leak, to meet the power battery shell strength and rigidity requirements.
4, lightweight aluminum automotive materials, low density, light weight, can reduce the weight of the vehicle, improve vehicle life.
