Square battery housing material 3003 aluminum plate

Automotive power battery aluminum shell products mainly use 3003 aluminum plate, which has easy processing and forming, high temperature corrosion resistance, good heat transfer and electrical conductivity. The aluminum shell of the power battery of 3003 aluminum alloy (except the shell cover) can be stretched and formed at one time, which can eliminate the box bottom welding process compared to the stainless steel shell. The use of 3003 aluminum alloy for packaging, the packaging process is very important in the production process of power batteries, because a good packaging process determines the safety and life of power batteries.

The main alloying element of 3003 aluminum plate is manganese, small density, soft material, with the advantages of easy overall stretching and forming of the aluminum shell of the power battery, the density of aluminum alloy is much smaller than that of traditional stainless steel packaging materials, which can realize the development of automobile lightweight.

At present, the development of aluminum plate for 3003 power battery shell has undergone a transformation from "0 state" to "H14" state. The root cause lies in the advancement of technology. As a traditional state of manual stamping, "O-state" material has the characteristics of low production efficiency and yield rate. The "H14" state material is more suitable for automatic semi-automatic punching, and the production efficiency is high. Therefore, some large domestic enterprises with strong scale and strength are currently based on the "H14" 3003 power battery shell.

As a large-scale aluminum processing enterprise, Haomei Aluminum has invested a lot of energy in the field of new energy vehicle manufacturing materials. 3003H14 power battery shell is the main material of its core power battery, and it is also one of the new products that the company has devoted itself to research. With the scientific and technological progress of new energy, 3003H14 power battery shell aluminum plate will usher in greater development opportunities.
