2. The development of automobile lightweight provides a broad growth space for the development of aluminum profiles
(1) traditional automobile lightweight application scenarios continue to expand
Aluminum was first used as a substitute for steel in the field of automobile material manufacturing. As early as 1899, European automobile enterprises used aluminum casting transmission case. With the passage of time, the range of automotive aluminum is becoming wider and wider. At present, the utilization rate of aluminum alloy in transmission case and heat exchange system is close to 100%, and the engine cylinder block, cylinder head and wheel have also reached a higher level. In the future, we will focus on the development of auto body, chassis and other parts, and the application range is expected to increase significantly. Lightweight is to reduce the weight of the vehicle as much as possible under 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. The fuel saving rate of different vehicle optimization schemes is analyzed and compared. Every 10% reduction of vehicle weight can reduce fuel consumption by 6-8%. Compared with other optimization measures, it has more obvious advantages in reducing fuel consumption and CO2 emission. In recent years, due to the increasingly strict requirements of environmental protection and energy saving, automobile lightweight has become an irresistible development trend. The density of aluminum is only 1 / 3 of that of steel, and it has good plasticity and recyclability, so it is an ideal lightweight material for automobile. With the development of technology, the application of aluminum alloy in wheel hub, engine, radiator and oil pipe will be deepened gradually.

With the introduction of aluminum profile and aluminum parts finishing technology, aluminum alloy parts for new energy vehicles are gradually expanded to the body, wheel, chassis, bumper anti-collision beam, floor, electric battery, energy absorption box, pedal, skylight slide, roof luggage bracket and seat. At the same time, compared with ordinary gasoline vehicles, new energy vehicles have lower carbon emissions and higher environmental protection. In recent years, China’s new energy vehicles maintain a high-speed development trend. In 2019, the output of new energy vehicles in China reached 1242000, a year-on-year decrease of 2.3%.
With the development and popularization of new energy vehicles, the future market demand for aluminum alloy in the field of new energy vehicles will be more vigorous.
(3) the permeability of aluminum alloy in the field of auto parts is gradually improved
By 2025, the aluminum alloy permeability of engine hood, bumper, door, trunk, roof and body structure will be 85%, 27%, 46%, 33%, 30% and 18% respectively, which is greatly improved compared with the current level.
Compared with foreign countries, domestic automobile enterprises are relatively backward in the application of automotive aluminum, especially aluminum alloy body. In recent years, with the development of Chery, BAIC, Weilai and other domestic automobile enterprises, as well as the production of Tesla, Jaguar Land Rover, GM Cadillac and other international giants in China, the rapid development of aluminum alloy in the field of auto parts has been promoted.
(4) with the development of automobile lightweight trend in China, the aluminum consumption per vehicle is gradually increased
According to the “made in China 2025 plan” issued in 2016, by 2020, through the application of high-strength steel, aluminum magnesium alloy and other composite materials in automobiles, the average vehicle weight reduction target will be 5% to 20%. Automobile lightweight transformation based on aluminum alloy is an important way of automobile lightweight.
According to the “energy saving and new energy vehicle development technology roadmap” prepared by China Automotive Engineering Society, China’s three-step plan for vehicle lightweight is planned to achieve the annual weight reduction of 10%, 20% and 35% in 2020, 2025 and 2030 compared with 2015, and the aluminum consumption per vehicle will reach 190kg, 250kg and 350kg respectively. In order to achieve this goal, China’s aluminum consumption for single vehicle will continue to increase. High strength steel, aluminum alloy and new materials are mainly used to replace automobile lightweight. By 2030, China’s demand for lightweight aluminum extrusion materials will reach 2.24 million tons.
