Aluminum alloy can be widely used in automobile industry, and the intensity of aluminum consumption increases gradually under the wave of lightweight. Aluminum alloy can be applied to the body, engine, wheel and other structural parts and components, in the context of the appeal of energy conservation and environmental protection and the progress of aluminum alloy technology, aluminum alloy in the automotive industry consumption intensity increased year by year. At present, automotive aluminum alloy is mainly die-cast aluminum alloy, and rolled plate is followed
At present, die-cast aluminum alloy is the main aluminum alloy used in automobile, and the proportion of rolled plate increases rapidly with the increase of aluminum used in automobile body. Cast aluminum alloy is the largest aluminum alloy used in most cars at present. It is widely used in wheels, engine parts, chassis, shock absorber support and space frame and other structural parts. These parts have a high aluminization rate. Compared with cast aluminum alloy, deformed aluminum alloy mainly plays a role of lightweight in car body, but due to low aluminization rate, the average application share in automobile is still less.
Compared with internal combustion engine vehicles, new energy vehicles use higher aluminum strength and deformed aluminum alloy. According to the statistics of Ducker Frontier, pure electric vehicles (BEV for short) generally use 101 kg extra aluminum than internal combustion engine vehicles. BEV eliminates the aluminum parts such as cylinder block, cylinder head and piston in the power assembly of internal combustion engine vehicles (ICE for short), as well as the valve body and clutch shell in the transmission system and transmission. Coupling, drive shaft and other aluminum parts, the amount of aluminum in this part is about 62 kg, and almost all of them are cast materials. The battery housing, electric traction system, body and opening and closing parts of the BEV require an additional 163kg of aluminum, less than a third of which is cast material, mainly aluminum.
The amount of BEV aluminum was higher, and the amount of extruded parts and aluminum plate increased.
In 2020, the aluminum consumption of new energy buses, hybrid passenger vehicles, pure electric passenger vehicles, traditional passenger vehicles and commercial vehicles is 232.2kg, 198.1kg, 157.9kg, 138.6kg and 122.6kg, respectively. Assessment of Aluminum Usage in China’s Automobile Industry 2016-2030 issued by International Aluminum Associate in 19, To the Chinese car models is analyzed and predicted by the aluminum, mainly divided into passenger cars, commercial vehicles, special vehicles and 2 / tricycle, passenger car passenger cars including internal combustion engine, pure electric passenger cars and hybrid passenger cars, commercial vehicles include passenger buses, new energy bus (fuel) and trucks, 2 / tricycle contains two/three rounds of motorcycle and two/three rounds of electric bicycle. From the trend, the amount of aluminum used in new energy buses is always higher than other models; By vehicle type, the aluminum consumption of new energy buses, hybrid passenger vehicles, pure electric passenger vehicles, internal combustion engine passenger vehicles and internal combustion engine commercial vehicles in 2020 is 232.2kg, 198.1kg, 157.9kg, 136.4kg and 70.3kg, respectively.
China’s production and sales of new energy vehicles have ranked first in the world for six consecutive years, and domestic sales of new energy vehicles continue to rise this year. Data from China Automobile Association show that in October 2021, the production and sales of new energy vehicles were 397,000 and 383,000 respectively, up 133.2% and 134.9% year-on-year respectively. From January to October, 2.566 million and 2.542 million units were produced and sold respectively, up 175.3% and 176.6% year-on-year respectively. Overall, the production and sales volume has maintained a year-on-year trend of rising since 2021.
At the same time, China has made it clear that all new cars sold must be electric by 2035, with a 50-50 mix of pure and hybrid vehicles. The Ministry of Industry and Information Technology also set a goal of increasing the number of hydrogen fuel cell vehicles to 100,000 by 2025 and one million by 2035. In 2025, China’s output of new energy vehicles may reach 7.48 million units, with a compound annual growth rate of 40.5% from 20 to 25 years. The annual compound growth rate of China’s new energy vehicle production capacity from 2020 to 2025 will reach 40.5%, and the output of new energy vehicles in 2025 will be 7.48 million.
Electric vehicles will show more promise and the aluminum industry will grow as a result. Electric vehicles are an industry that increasingly relies on off-the-shelf aluminum and aluminum alloys. As its market share increases, aluminum for new energy vehicles will grow rapidly in the next five years.
