Aluminium plate Supplier
Aluminium plate Supplier
The power battery system is the core driving force of electric vehicles. It is composed of battery modules, electrical systems, thermal management systems, battery management systems, housings and other parts.
The main function of the car battery shell is to carry and protect the battery module, and it needs to meet mechanical requirements such as strength, rigidity, and collision safety. The battery shell material usually chooses 3003 aluminum alloy. It can increase the conductivity of the power battery and contributes to the lightweight of car battery.
The energy storage system battery pack aluminum cooling plate made of two aluminum plates, the main process is hot rolling, blow molding, leakage test, and insulation coating etc. It has the good tightness and high strength of the combination between aluminum plates, which can avoid leakage of coolant in the flow channel, high processing efficiency, less pollution and more environmental protection.
3003 aluminum alloy for car body is a typical Al-Mn alloy. Its main alloy elements have Mn, Cu, Mg, Si, Fe, etc. These five alloys play different roles in it. For example, Cu and Mg improve strength and hardness. Mn improves corrosion resistance, Si can enhance the heat treatment effect of magnesium-containing aluminum alloys, and Fe can improve high-temperature strength.
It has good formability, good corrosion resistance and weldability. It is often used to make power battery shells in lightweight automobiles, cookware, food storage devices, tanks and silos on transportation equipment, metal sheet pressure vessels and pipes
