Aluminium sheet materials for body and chassis
With the continuous development of the automobile industry, aluminum is widely used in automobile manufacturing as a lightweight, high-strength and corrosion-resistant material. The application of aluminum in automobiles can not only reduce the body weight, improve fuel efficiency, but also increase the safety performance and ride comfort of the vehicle.
