Advantages of Automotive Aluminum Alloy Parts
The industrialization of automobiles has accelerated the development of China’s economy, but we are also facing issues of severe environmental protection and energy conservation and emission reduction. Automobile lightweight has become an important trend in the development of the automobile industry. The application of aluminum alloy materials has effectively alleviated this problem. The various properties of aluminum alloys have been fully demonstrated in the process of reducing the weight of the car. After optimizing and transforming the structure and parts of the car, the weight of the car body has been effectively reduced. The weight of the engine and chassis is also reduced. However, it should be noted that the light weight of automobiles cannot sacrifice its basic functions, and the goal of energy saving and emission reduction can be achieved on the premise of gradually improving the functions of automobiles.
Advantages of automotive aluminum alloy parts
Among the various metals we use at present, aluminum alloy can be ranked second, especially in the transportation industry. The consumption of various aluminum alloy parts is very high, and most of them are mainly used in automobile production. The energy consumption of automobiles has always been high, because the energy consumption generated by the weight of the automobile itself accounts for a large part. Therefore, some light materials have been used in the process of automobile production and processing, among which aluminum alloys stand out and have successfully replaced steel.
Automobile lightweight is an important topic in the development of automobile industrialization. The development of automobile lightweight does not damage the quality and use function of automobiles. It can only be achieved through technological innovation. The use of lightweight materials in auto parts to reduce their weight, especially in the engine part. The requirements for power output, low noise, low vibration should be met. The comfort and safety of the car are the key concerns for consumers. Only when the above conditions are met can automobile manufacturers develop healthily in the fierce competition. At present, aluminum alloy is one of the main materials to meet the lightweight of automobiles. It can not only meet the requirements for the performance of materials for automobiles, but also ensure low-cost production. Among various auto parts, the main parts using aluminum alloys are concentrated in the body chassis and engines. Usually, the density of aluminum alloys is about 2.7g/cm3, while the density of steel is about 7.8g/cm3. Using aluminum alloys instead of steel has greatly reduced the weight of the engine, and at the same time the weight of the car body and chassis has also been reduced; the wheel load supporting the weight of the car body has also been reduced. According to the balanced system theory, when the weight of a certain component is reduced by 10%, the weight of the entire system can be reduced by more than 20%. In the case of a substantial reduction in body weight, the fuel consumption of the car is significantly reduced, and the driver's control over the car is also improved. In addition, the recycling value of aluminum alloy is high, and aluminum alloys can be recycled and reprocessed after the car is scrapped, which can realize recycling and reduce the waste of resources, and is in line with the strategic goal of sustainable development. Therefore, the advantages of aluminum alloys are very significant.
In recent years, many automobile companies have joined the research on aluminum alloy automobile bodies and parts. Some high-end automobile brands have achieved good results in the application of aluminum alloys, and the application ratio is already quite high. For example, in the body-in-white of the Audi A8, the proportion of its body aluminum alloy has reached 65.3%, while the proportion of Tesla's car body aluminum alloy has reached 97%, which is also the car company with the highest proportion of aluminum alloy in the world. China's auto industry started relatively late. At present, NIO's ES8/ES6 series has a relatively high proportion of aluminum alloys used in body-in-white, which has reached 96%. However, other car companies only started, and aluminum alloys are only applied to some components with relatively simple structures.
