Abstract: under the current manufacturing technology and technical level, the lightweight of the car body is an important means to solve the overloading and energy saving and emission reduction of heavy-duty vehicles, and aluminum alloy is used to make the car body plate to reduce the weight of the car body. it can improve the service life of the product on the premise of reducing self-weight.
In recent years, with consumers' demand for fuel saving, durability, safety and high performance, as well as the gradual enhancement of environmental awareness, the major car companies' choice of car body profiles is also constantly innovated with the needs of consumers. automobile lightweight has become the focus of attention of the major automobile companies. How to use aluminum profiles to reduce body weight and improve the performance of automobile products has become the key direction of technology research and development of automobile enterprises.
The so-called automobile lightweight is to reduce the vehicle weight as much as possible under the premise of ensuring the vehicle strength and safety performance, so as to improve the vehicle power performance, reduce fuel consumption and reduce exhaust pollution. Therefore, it has become a hot spot to minimize the self-weight of the car.
In the "Evaluation report of Aluminum used in China's Automobile Industry (2016Muth2030)" commissioned by CM Consulting Company commissioned by the International Aluminum Association, it is predicted that the aluminum consumption of China's automobile industry will increase from 3.8 million tons in 2018 to 9.1 million tons in 2030, with an annual compound growth rate of 8.9%. The application of lightweight automotive products has further stimulated the increase of aluminum consumption in the automotive industry.
The lightweight of cars is not just about weight loss.
Aluminum alloy is mainly used in car body, wheel hub, chassis, anti-collision beam, floor, power battery, seat and other parts. According to the classification of processing forms, automotive aluminum is mainly divided into three forms: die-casting, extrusion and Calendering, in which extruded parts are mainly used in automobile seat frame, luggage rack, door beam and so on, while Calendering parts are mainly used to produce aluminum sheet for car body.
Under the current manufacturing technology and technical level, the lightweight of the car body is an important means to solve the overloading and energy saving and emission reduction of heavy-duty vehicles. Using aluminum alloy to make the car body plate to reduce the weight of the car body can improve the service life of the product on the premise of reducing the self-weight. The density of aluminum alloy material is only 1max 3 of steel, which has obvious effect of weight loss and energy saving, and can better improve ride comfort on the premise of ensuring safety.
In addition to weight loss, another growing advantage of aluminum is that it has considerable advantages in terms of application technology, operational safety and recycling. Recycling is easier for other components, as evidenced by the increase in the use of recycled aluminum in China's auto industry.
With the implementation of the national energy saving and emission reduction policy, automobile lightweight products have been widely used in automobile production. Yuefeng aluminum firmly seizes this development opportunity on the road of development, deeply ploughing in the field of automobile lightweight industry, and has independently developed the first pure electric all-aluminum frame, which reduces the weight of traditional car body by 40%. Cooperation agreements have been reached with domestic well-known automobile brands such as Geely, Chery and Haima Automobile. It has opened up a new sales orientation in the diversified application needs of the automobile, which helps the automobile application of aluminum alloy materials.
