Why choose 3003 H14 aluminum alloy material in the lithium battery aluminum casing of new energy vehicles and energy storage?
In the power battery system of new energy vehicles, the battery shell accounts for about 20 to 30% of the total weight of the system and is the main structural component of the battery. For the sake of lightweight, square power battery shells are generally made of 3003 aluminum plates, which require high material performance and are made of international standard materials. Recycled materials are strictly prohibited. Both anti-corrosion and explosion-proof properties are the best.
3003 aluminum plate has many advantages when used in new energy power battery shells
1. Good processability. The 3003 aluminum alloy power battery aluminum shell (except the shell cover) can be stretched and formed at one time. Compared with the stainless steel shell, the bottom welding process of the box can be omitted.
2. Light weight. The mass of the battery box has a great influence on the quality of the entire battery module. The density of aluminum alloy is higher than that of traditional stainless steel. In order to reduce weight, it is an inevitable choice to use 3003 aluminum alloy material to make the battery case.
3. Good heat transfer. Power batteries will generate heat when working for a long time, and the battery casing needs to have good heat dissipation.
4. Good corrosion resistance. 3003 aluminum plate is an aluminum-manganese alloy. Due to the manganese alloy element, the product has excellent anti-rust properties and is also called anti-rust aluminum plate.
In view of the above advantages, many companies currently use 3003 aluminum plates as power battery casing materials. With the country's emphasis on energy conservation and emission reduction and breakthroughs in aluminum alloy body panel technology, especially the increase in the production of new energy vehicles, the aluminization rate of automobile bodies will gradually increase, and the demand for aluminum for power battery shells will also increase.
Features of power lithium battery aluminum case:
1. The elastic coefficient is small, there is no spark caused by collision and friction, and it performs best in automobile technology.
2. No metal pollution, no toxicity, and no volatile metals in the surface oxide layer.
3. Compared with other metal materials, it has low density and light weight.
4. It has strong plasticity and good productivity, which has great advantages for production.
5. It adopts two processes of hot and cold processing, which has strong corrosion resistance.
6. It has good casting performance, very high aluminum content and abundant reserves.
7. It has good ductility and can be used to make lightweight alloys with many metal elements. The material is of high quality.
8. Good surface treatment performance.
9. It has stable chemical properties, is non-magnetic and can be recycled repeatedly. It is a benign and recyclable metal material.
