New energy battery aluminum sheet metal shell

The aluminum shell of the battery has high specific strength, specific modulus, fracture toughness, fatigue strength and corrosion resistance stability. Because aluminum alloy materials have the characteristics of low density, non-magnetic, stable alloy phase at low temperature, low specific resistance in the magnetic field, good air tightness, fast attenuation of inductive radiation energy, etc., they have been widely used in aviation, aerospace, high-speed trains, machinery manufacturing, shipbuilding, automobile and chemical industry.
The surface treatment of battery aluminum shell is mainly electrostatic spraying, and its color is also very rich. Its color generally includes off white, dark gray, black, military green, etc.
The aluminum shell of battery has the advantages of aluminum alloy, so it is also light and durable when forming.
The aluminum shell of the battery has stronger plasticity, better productivity compared with other profiles, and good castability, so it has good advantages for production.
The aluminum shell of the battery will be treated by hot and cold processes, so that the aluminum shell of the battery will have strong corrosion resistance. Therefore, the safety of aluminum battery is better.
This kind of shell also has good ductility. It can be made of light alloy with many metal elements, and the material is high-quality. Its chemical properties are stable, non-magnetic, and can be recycled. It is a benign and recyclable metal material.
