As the core component of new energy vehicles, the power battery is made of aluminum alloy, which is an excellent choice for power battery packaging. It has good heat transfer and electrical conductivity, is easy to stretch and form, has excellent sealing performance and compression resistance, and can reduce the weight of the vehicle.
For the consideration of light weight and workability, the battery shell of new energy vehicles generally adopts 3003 aluminum alloy plate. It belongs to aluminum-manganese alloy, and the main alloying element is manganese. This material is easy to form, high temperature corrosion resistance, good heat transfer and electrical conductivity. The aluminum power battery case (except the case cover) of 3003 aluminum alloy can be drawn and formed at one time. Compared with the stainless steel shell, the welding process of the bottom of the box can be omitted. Moreover, the boiling point temperatures of aluminum and manganese are not much different, so there will be no problems such as the deterioration of the quality of the weld due to the burning of metal elements during welding.
3003 aluminum alloy has been used in battery packaging by many companies. What is its rate?
Power battery shell materials generally use 3003-H14, with a thickness of 0.8-3.0mm. For different specifications, the price of the manufacturer is different. In addition, due to the different production levels, input costs, and sales models of each manufacturer, the product quotations are also different.
As a private listed company, Mingtai Aluminum has been deeply involved in the aluminum processing industry for more than 20 years. The company can produce a variety of aluminum for new energy vehicles batteries. At present, the production and development process of aluminum alloy materials such as power battery top plates, trays, deep-drawn battery shells, water-cooling plates, and battery soft connections has matured.
