Die-casting aluminum Application fields of New energy Vehicle

Die-casting aluminum Application fields of New energy Vehicle

In recent years, aluminum used in automobiles is mainly concentrated in parts such as drive systems, gearboxes, transmission systems, and brake systems. In the future, with the further improvement of the application technology of aluminum alloy materials, its application range in the automotive field will gradually extend to For large parts such as hood, fender, door, rear compartment, roof, and whole body, which are mainly made of steel castings, aluminum for automobiles is expected to continue to grow in the future. Aluminum for automobiles is mainly used in die-casting, Three forms of extrusion and calendering have been put into use, of which die castings account for about 80%.

The lightweight of the "three electric system" of new energy vehicles is an important direction to realize the lightweight of the whole vehicle. The aluminum alloy die-casting is the main driver to realize the lightweight of the "three electric system". Power batteries, drive motors, and electronic control systems are the core components of new energy vehicles, collectively known as the three-electric system, and are the key to determining vehicle performance. The power battery is the "energy" source of new energy vehicles, and the drive motor and electronic control system are used as substitutes for traditional engine functions, and their performance directly determines the main performance indicators of electric vehicles such as climbing, acceleration, and maximum speed. From the perspective of the manufacturing cost of new energy vehicles, the three-electric system accounts for about 50% of the vehicle cost.

Aluminum alloy die-casting products are widely used in three-electric systems to help new energy vehicles achieve lightweight and improve battery life. At present, the battery housing, motor housing, electronic control housing, battery components, battery box, etc. in the three-electric system are all using aluminum die-casting products, and the consumption is constantly increasing.
