In recent years, aluminum alloys have been widely used in the automotive field. With the vigorous promotion and application of sustainable development strategies, automotive lightweighting has become the trend of automotive progress. In the process of lightweighting of automobiles, aluminum alloy materials are particularly important, which are mainly used to transform and replace car body raw materials. Vehicle lightweighting mainly includes three categories: body lightweighting, chassis lightweighting and engine lightweighting. Its main purpose is to reduce vehicle weight by using lighter raw materials under the background of ensuring performance, thereby achieving the goal of energy conservation and environmental protection. So, what are the special meanings of aluminum alloys in automotive lightweighting:
One: Aluminum alloy is easy to recycle and reuse. Aluminum products are not prone to corrosion or slight corrosion during the application process. Among the conventional raw materials used in the industry, the recycling value of aluminum materials is very large. Although its recycling performance is non-standard aluminum, it is higher than other commonly used metals.
Two: weight loss and energy saving and environmental protection have achieved remarkable results. Aluminum has good mechanical properties, its density is only 1/3 of that of steel, has good thermal conductivity, and the oxide film naturally formed on the surface of aluminum has good corrosion resistance. target raw material.
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, and the car is more comfortable and stable during driving. Because of the good performance of aluminum alloy, it has a significant advantage in the 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 protect the driver and passengers behind.
