What are the advantages of the battery aluminum shell?

At present, many power lithium battery casings on the market are aluminum battery casings. The extensive application of battery aluminum shells has also driven the development of the battery shell industry. So what are the advantages of aluminum battery casings? Why not use steel or plastic casings but aluminum casings as battery casings? Today, subcontinent battery casing manufacturers will talk about some of the advantages of battery aluminum casings: What are the advantages of aluminum battery casings ? 1. The battery aluminum shell has high specific strength, specific modulus, fracture toughness, fatigue strength and corrosion resistance stability. Because of the low-density characteristics of aluminum alloy materials, non-magnetic and stable alloys, in the low temperature stage, they have less resistance to magnetic fields, good air tightness, and rapidly attenuating induced radiation. It has been widely used in aviation, aerospace, high-speed trains, and machinery manufacturing. , Transportation and chemical industry. 2. The surface treatment of the battery aluminum shell is mainly through electrostatic spraying, and its color is also very rich. The colors are generally off-white, dark gray, black, and army green. 3. The battery aluminum shell has the advantages of aluminum alloy, light weight, and durable molding. 4. The battery aluminum shell has strong plasticity, production performance is better than other profiles, and has good casting performance, which has better advantages in production. 5. Subcontinent battery aluminum shell adopts two processes of cold and hot treatment, so that the battery aluminum shell has strong corrosion resistance. This makes aluminized batteries safer. 6. The shell also has good ductility, making it a light alloy with many metal elements. Its chemical properties are stable, non-magnetic, recyclable, and it is a good recyclable metal material. Now you understand the advantages of aluminum battery casings! In addition, the elasticity of battery aluminum casings is also poor, the density of other metal materials is also very small, and the weight is also very light, so it can be said that the aluminum casing is a power lithium battery The best match.
