Why Is 3003 Aluminium Sheet Used for Power Battery Shell

New energy vehicles are of great significance in saving resources and protecting the environment. In order to increase the mileage, new energy electric vehicles need a large number of lithium battery combination modules. Each module is composed of several battery boxes. To reduce weight, aluminum alloy has become an ideal choice for power battery shell.

The batteries that provide driving power for electric vehicles are called power batteries, including traditional lead-acid batteries, nickel-metal hydride batteries, and the emerging lithium-ion batteries. The car battery shell material is preferably 3003 aluminium sheet.

3003 aluminum plate has good formability and is mainly used in deep drawing field like stamping parts, models, shells, etc. The power battery shell made of 3003 aluminum alloy is of impact resistant and not easy to break and leak, which can meet the strength and rigidity requirements of the power battery shell.

In addition, the aluminum alloy has low density and light weight, which can reduce the weight of the battery, increase the density of the battery capacity, make the battery work stable, and indirectly reduce the with weight of the whole car.

5052 aluminum sheet is also used in the car, mainly for the interior panel. What are their differences? The tensile strength of 3003H24 aluminum plate is 145-195Rm/MPa, while the tensile strength of 5052H24 aluminum plate is as high as 230-280Rm/MPa, which is much higher than 3003H24 aluminum plate.

The extension strength of 3003H24 aluminum sheet is 115Rm/MPa, and the extension strength of 5052H24 aluminum sheet is 150Rm/MPa. Therefore, the performance of 5052 aluminum plate is significantly better than that of 3003 aluminum plate. But 5052 aluminum price is also a little higher.
