                                      Among the 124 existing industries in the national economy, the automobile industry is one of the most widely used aluminum industries. According to Chen Yilong, director of the expert committee of the automobile lightweight technology innovation alliance of China Automotive Engineering Society, China's current automobile gasoline and diesel consumption accounts for 65% of the gasoline and diesel consumption, and 70% of the new oil consumption each year is consumed by new cars. According to the research conducted by Heidelberg company in 2011, 10% weight reduction of passenger cars, light commercial vehicles, medium-sized trucks, city buses and long-distance buses can save 5.7%, 5.7%, 5.6% and 2.4% respectively. It can be seen that the benefits of vehicle lightweight will be great, at the same time, it can also reduce greenhouse gas emissions, social benefits are huge.

                                      In 2019, the production and sales of China's automobiles will reach 25.721 million and 25.769 million respectively; the production and sales of new energy vehicles will be 1242000 and 1206000 respectively. According to the statistics of the world Aluminum Association, there are 72.3 million light vehicles in the world in 2019. The aluminum consumption in North America is mostly 148kg / vehicle, while that in China is only 100kg / vehicle. According to the author's estimation, the aluminum consumption of light vehicles in North America will reach 180kg / vehicle in 2019, while that of China will be about 120kg / vehicle. If by 2025, China's light vehicle production can reach 25 million units, and the aluminum consumption can reach 180kg / vehicle, then the aluminum consumption will reach 3600kt, which is a very encouraging number.

                                      It should be pointed out that at present, the casting aluminum alloy for automobile has been basically saturated, and the main increase is aluminum, accounting for more than 85%. There are a lot of parts and components that need to be aluminized on the automobile, such as: panel parts (passenger cars), five large commercial vehicles (front and rear wall, ceiling, left and right wall), passenger car body, anti-collision beam (beam, energy absorption box, connecting plate), front subframe, instrument panel beam, water-cooled shell of new energy vehicles, battery pack, battery pack frame, water-cooled panel, engine front bracket and bottom It includes suspension parts, truck cab, truck chassis, aluminum light truck container, air reservoir, etc.
