In recent years, aluminum alloy is widely used in the field of automobile. With the promotion and application of sustainable development strategy, automobile lightweight has become the trend of automobile progress. In the process of automotive lightweight, aluminum alloy material is particularly important, which is mainly used in the transformation and replacement of body raw materials. Automotive lightweight mainly includes body lightweight, chassis lightweight and engine lightweight. Its main purpose is to reduce vehicle weight by using lighter raw materials under the background of ensuring performance, so as to achieve the goal of energy conservation and environmental protection. So, what are the special significance of aluminum alloy in automobile lightweight?
A: Aluminum alloy is easy to recycle and reuse. Aluminum products in the application process is not easy to appear corrosion or slight corrosion phenomenon, industry by using conventional materials, aluminum recycling value is very big, in aluminum - aluminum - applications - made of aluminum recycling aluminum - secondary circulation, although the regeneration performance is the aluminum, but is higher than other metals are a relatively common.
Two: weight reduction and energy conservation and environmental protection have achieved remarkable results. Aluminum has good mechanical properties, its density only accounts for 1/3 of that of steel, good thermal conductivity, and the oxide film formed naturally on the surface of aluminum has good corrosion resistance. Therefore, aluminum is the raw material to achieve the goal of lightweight automobile.
Three: improve the reliability and comfort of passengers. Aluminum alloy car is to reduce the weight of the car without reducing the capacity of the car, the car is more comfortable and stable in the process of driving. Because of the good performance of aluminum alloy, it has a significant advantage in the link of collision performance. Once a collision occurs, the deformation area of the front end of the car will be wrinkled, which can absorb a large impact force, and then protect the driver and passengers behind.
