The alloy material can be described as the hot fried chicken in the car circle at present. From the body frame to the chassis suspension, if the aluminum alloy material is used, it seems that this car can be high-end and high-end. Audi is an early car brand that applied a large number of aluminum alloys to the automotive field. It began to develop aluminum bodywork in 1983. Compared with the steel body of earlier times, the aluminum alloy body has obvious advantages in weight. Nowadays, most high-end models use aluminum alloy in large quantities.

However, as carbon fiber materials with higher strength and lighter weight were invented, the status of aluminum alloy was significantly reduced, especially in the field of supercars, carbon fiber has the potential to replace aluminum alloy.

The new Audi R8 is a good example. The old Audi R8 was proud of its frame using a large number of aluminum alloy materials. Now the new Audi R8 has adopted a large number of carbon fiber materials in the frame as a promotional highlight.

In addition to the use of carbon fiber in places where we can't see the frame, the exterior and interior parts of the car body are also increasingly using carbon fiber materials. In some super sports cars, the wheels are even made of carbon fiber. The status of aluminum alloy material is gradually being replaced.
