Aluminum application: opportunities brought by new energy vehicles to the aluminum industry

with the substantial improvement of new energy vehicles in the fields of household vehicles, official vehicles, buses, taxis, logistics vehicles, etc., according to the materials, the annual sales volume of new energy vehicles in China in 2020 will reach more than 5% of the total demand of the automobile market, and will initially be market-oriented, enterprise oriented A new energy vehicle industry system with strict separation of industry, University, research and application. By 2025, it will increase to about 20%, forming an independent, controllable and sound industrial chain. Under the national total carbon emission goal and the demand of the primary energy alternative catalogue, the proportion of annual sales of new energy vehicles in 2030 will continue to improve significantly, with a range of more than 10 million vehicles

it is not too late for China to implement the strategy of new energy vehicles. As early as 2001, the development of new energy vehicles was included in the "863" serious scientific and technological topic during the Tenth Five Year Plan period. In recent years, in order to promote the consumption of new energy vehicles, governments at all levels have also implemented policies such as car purchase subsidies and licensing priority. The demand and development of new energy vehicles will drive the development of various automotive batteries, body lightweight and auto parts industries in the new energy era. At the same time, it will also bring infinite market opportunities to China's aluminum industry

thank you for your new energy. Unlike traditional cars, cars use batteries as power to drive cars. It is limited by the weight of power batteries, the mileage of power batteries, and the high voltage of automobile energy conservation and emission reduction policies. In vehicle design and data application, the lightweight of its body has become the first problem that car enterprises should consider. Therefore, battery driven new energy vehicles are more urgent to reduce body weight than traditional vehicles. This has also opened up a broader market space for lightweight materials such as aluminum

in automobile lightweight materials, the comprehensive cost performance of aluminum alloy profiles is higher than that of steel, magnesium, plastics and composite materials. No matter the application technology is due to our successful technology, operation safety and recycling applications, it has comparative advantages. As long as the density of aluminum material is 1/3 of that of steel, its weight reduction and energy saving effect are obvious, and it can better improve the comfort of riding on the premise of ensuring safety. At the same time, aluminum materials are more and more easy to recycle. The comprehensive cost performance advantage of aluminum determines it to be the choice of automotive lightweight applications

the application parts of aluminum in new energy vehicle parts mainly include body, wheel hub, chassis, crash beam, floor, power battery, seat, etc. According to the classification of processing methods, automotive aluminum is mainly divided into three forms: die casting, extrusion and calendering. The consumption of die castings accounts for about 80%, and the consumption of extrusion and calendering accounts for 10% respectively. It is expected that the total demand for vanadium will increase by about 11%. Die castings are mainly used in the engine, wheels and other parts, extrusions are mainly used in the seat frame, luggage rack, door beam and so on, and calendered parts are mainly used in the consumption of aluminum plates for car bodies

among them, the body includes the body frame made of high-performance aluminum profile and the skin and door made of high-precision aluminum plate; Aluminum alloy hub (cast aluminum hub or forged aluminum hub); The chassis includes high-strength and large section aluminum structural parts and aluminum alloy forgings; Crash beam bumper made of profile; New energy bus floor; Lithium ion batteries include battery positive aluminum foil, battery aluminum shell and battery aluminum tray (all European and American battery trays are made of aluminum alloy, while domestic battery trays are made of both aluminum alloy and stainless steel); New energy bus seat system, etc

in the past, new energy vehicles mostly used steel materials to manufacture power battery trays for electric vehicles. Now many enterprises mainly use aluminum alloy profiles. The density of aluminum alloy profile is 2.7g/cm3. Aluminum alloy material has obvious advantages in terms of contraction or welding. The density of magnesium alloy is 1.8g/cm3, and that of carbon fiber is 1.5g/cm3. Using these materials to consume battery trays will greatly improve the lightweight of new energy vehicles

it is understood that the battery aluminum tray mainly adopts 6-series aluminum profiles. Good plasticity and corrosion resistance, especially no stress corrosion cracking tendency and good welding performance make the 6 series aluminum profile extremely suitable for the application of this project. In order to ensure the production and quality, advanced welding technologies such as friction stir welding are required to ensure the integration of products

new energy vehicles use more aluminum than ordinary vehicles. The rapid development of new energy vehicles in China will certainly promote the development potential of aluminum in the new energy vehicle market segment, and aluminum processing enterprises seize this opportunity to develop high-performance and applicable aluminum or deep processed aluminum components, Undoubtedly, it also provides a new sales orientation for enterprises to open up and maintain a close technical exchange with the Fifth Academy of Aerospace Science and technology in the diversified application needs of new energy vehicles
