Lightweight vehicles promote the growth of aluminum consumption in the automotive industry

With the increase in the production and sales of automobiles, the energy consumption and pollutant emissions in the process of automobile production and use are increasing, and at the same time, the pollution to the environment is becoming increasingly prominent. Therefore, in order to promote the sustainable development of the automobile industry, realize the lightweight of automobiles, save energy and reduce emissions, and improve the stability and dynamic performance of automobiles during driving, it has become the focus of current major automobile companies. How to use aluminum alloy materials to reduce the weight of the car body and improve the performance of automobile products has become the key direction of technology research and development of car companies.

The so-called lightweight vehicle is to reduce the weight of the vehicle as much as possible on the premise of ensuring the strength and safety performance of the vehicle, thereby improving the power performance of the vehicle, reducing fuel consumption and reducing exhaust pollution. Therefore, minimizing the weight of the car has become a current hotspot.

Application of Aluminum Alloy in Automobile Lightweight

The application of aluminum alloy in automobile lightweight mainly includes aluminum alloy forgings, metal die castings, aluminum alloy extrusion and drawing products and other applications.

Cast aluminum alloys are the most widely used in the current lightweight process of automobiles, mainly used in the engine, chassis, wheel hub and other structures of automobiles. The engine has always been called the "heart" part of the automobile. The application of aluminum alloy on the parts can not only effectively reduce the overall weight of the engine, but also dissipate the heat generated in the engine working process in time to improve the working efficiency of the engine.

In the "Assessment Report of Aluminum Consumption in China's Automobile Industry (2016-2030)" commissioned by the International Aluminum Association, it is predicted that the amount of aluminum used in China's automobile industry will increase from 3.8 million tons in 2018 to 910 million tons in 2030. 10,000 tons, with a compound annual growth rate of 8.9%. The application of automotive lightweight products has further stimulated the increase in the amount of aluminum used in the automotive industry.

The advantages of aluminum alloys go beyond weight reduction

The use of aluminum alloy parts in the car can effectively reduce the weight of the car, lower the center of gravity of the car, and truly realize the lightweight of the car. After the car is lightweight, the acceleration performance of the car will be improved during car driving, and the car will be more stable and comfortable to drive, and noise and vibration will also be improved.

In addition to weight reduction, another significant advantage of aluminum alloys is their good recyclability. Aluminum is a light metal with good electrical and thermal conductivity, as well as good corrosion resistance. At the same time, the machining performance of aluminum alloy is better than that of traditional metal materials. The melting point of aluminum is low, and the recovery rate of aluminum in the whole process of use and recycling is not less than 90%. An ideal material, this characteristic of aluminum alloys further drives the demand for aluminum in the automotive industry.

With the implementation of the country's energy conservation and emission reduction policies and the continuous innovation and development of the automotive industry, automotive lightweight products have been gradually applied to automotive production. On the road of development, GDAA firmly seizes this opportunity of development, deeply cultivates the automotive lightweight industry, and has successively reached cooperation with well-known domestic and foreign auto brands such as FAW-Volkswagen, Geely, Great Wall Motors, etc., to help the development and application of lightweight automobiles in my country.
