SMM Network News: among the existing 124 industries in the national economy, the automobile industry is one of the most widely used areas of aluminum. According to Chen Yilong, director of the expert committee of the Automotive lightweight Technology Innovation Alliance of the Chinese Academy of Automotive Engineering, China's current automotive gasoline and diesel consumption accounts for 65% of gasoline and diesel consumption, and 70% of the new oil consumption is consumed by new cars every year. According to a survey conducted by Heidelberg in 2011, passenger vehicles, light commercial vehicles, medium trucks, city buses and long-distance buses can save fuel by 5.7%, 5.7%, 5.7%, 5.6% and 2.4%, respectively. It can be seen that the benefits of lightweight vehicles will be great, at the same time, it can also reduce greenhouse gas emissions accordingly, and the social benefits are also huge.
In 2019, China's automobile production and marketing completed 25.721 million and 25.769 million respectively, and new energy vehicles produced and sold 1.242 million and 1.206 million respectively. According to the statistics of the World Aluminum Association, there are 72.3 million light vehicles in the world in 2019, of which 148kg/ is the most used in North America and only 100kg/ in China. According to the author's estimate, the amount of aluminum used for light vehicles in North America has reached 180kg/ in 2019, while that in China is about 120kg/. If the output of light vehicles in China can reach 25 million and the consumption of aluminum can reach 180kg/ by 2025, the consumption of aluminum will reach 3600kt, which is such a gratifying and encouraging figure.
It should be pointed out here that at present, the cast aluminum alloy for automobile has been basically saturated, and the increase is mainly aluminum, accounting for more than 85%. There are still a lot of aluminized parts on the car. Mainly include: panel panels (passenger cars), five major pieces of commercial vehicles (front and rear, ceiling, left and right), passenger car body, anti-collision beam (beam, energy absorption box, connecting plate), front subframe, instrument panel crossbeam, new energy vehicle water-cooled housing, battery package frame, water-cooled plate, engine front bracket, chassis suspension, truck cab, truck chassis, all-aluminum light truck carton, Gas reservoir, etc.
