Automotive aluminum alloy plates for sale and automotive safety

The natural advantage of aluminum is that it is less dense, only one-third of steel. At the same volume, the weight is one-third of steel, so automotive aluminum alloy plates are still of great use in body lightweight. The most valuable part of the automotive aluminum alloy plate is the cover, after all, strength is less important in this position. As for the parts related to structural safety, it depends on the design level to grasp the whole.

Where are automotive aluminum alloy plates used on the body, and how to use them? A basic principle: the right material is used in the right place. In other words, different locations have different needs and different materials. One of the most important aspects to consider in the choice of automotive materials is safety in the face of a crash. For crash safety, the body can be divided into two main areas: the energy absorption zone and the safety zone. The front and rear positions of the body can be considered as energy-absorbing areas, while the position of the middle passenger sitting is defined as a safety zone.

Different regions have very different requirements for automotive aluminum alloy plates. For example, the front and rear parts of the car include front and rear side members, energy absorption boxes and other parts. The main function required is energy absorption for collisions from the front and rear ends. The area enclosed by strength and deformation can be roughly thought of as the ability of a material to absorb energy. Of course, we don't want these energy-absorbing parts to break off prematurely during the collision process, so having a certain elongation is a basic requirement for automotive aluminum alloy plates. The second need is intensity. The intensity should not be so strong that it transmits the main energy backwards, nor too weak to achieve the function of absorbing enough energy. Suitable strength and good deformation ability are the requirements of these parts. 6 series 7 series aluminum alloy, 600MPa grade high-strength steel are suitable choices.
