With the increase of automobile production and sales, the energy consumption and pollutant discharge produced in the process of automobile production and use are increasing day by day, and at the same time, the pollution brought to the environment is also becoming more and more prominent. Therefore, in order to promote the sustainable development of the automobile industry, realize automobile lightweight, energy saving and emission reduction, and improve the stability and dynamic performance of automobiles during driving, it has become the focus of major automobile companies. How to use aluminum alloy materials to reduce the weight of the vehicle body and improve the performance of automobile products has become the key direction of technology research and development of automobile enterprises.

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, so as to improve the power performance of the vehicle, reduce fuel consumption, and reduce exhaust pollution. Therefore, minimizing the dead weight of automobiles has become a current hot spot.

Application of Aluminum Alloy in Auto Lightweight

The application of aluminum alloy in automobile lightweight mainly includes the application of aluminum alloy forgings, metal die castings, aluminum alloy extruded and drawn products and so on.

Casting aluminum alloys are the most widely used in the current lightweight process of automobiles. They are mainly used in the structures of automobile engines, chassis, and hubs. The engine has always been known as the "heart" component 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, improving the working efficiency of the engine.

In the "Assessment Report on Aluminum Consumption in China's Automobile Industry (2016-2030)" commissioned by CM Consulting Company, it is predicted that the aluminum consumption in China's automobile industry will increase from 3.8 million tons in 2018 to 9.1 million in 2030. million tons, with a compound annual growth rate of 8.9%. The application of automotive lightweight products has further stimulated the increase in aluminum consumption in the automotive industry.

The advantage of aluminum alloy is not only to reduce weight

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

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

With the implementation of the country's energy saving and emission reduction policies and the continuous innovation and development of the automobile industry, automobile lightweight products have gradually been applied to automobile production. Haomei New Material firmly grasps this good development opportunity on the road of development, deeply cultivates the field of automobile lightweight industry, and has successively reached cooperation with Mercedes-Benz, BMW, Honda, Toyota, Geely, Great Wall Motors and other well-known domestic and foreign automobile brands to help my country's automobile industry Lightweight development applications.
