Automotive Aluminum - Analysis of Automobile Body Aluminum Sheet Project

Since the beginning of the new century, the automobile industry has been forced by the environmental regulations and global warming to reduce the quality of the car itself. At the moment, the most effective measure to reduce the car's own quality is to make spare parts with as much aluminum as possible, and the full aluminization of the body is a shortcut to do this. Since 2008, industrialized countries have set off a wave of renovation and expansion of new ABS projects. As of 2015, there are 30 projects in the world that have been built and under construction, with a total production capacity of 4,405 kt / a, of which 8 production capacity in China is At 1425 kt/a, the United States is 1810 kt/a, accounting for 41.1% of the world.

Automotive body aluminum sheet is abbreviated as ABS. It is a high-precision aluminum alloy sheet for stamping passenger car body parts. It is 0.8mm~1.8mm thick and ≤2200mm wide. It has the highest technical threshold in 4 kinds of high-precision rolled aluminum products (FRPs). The other three products are aerospace aluminum alloy plates, PS and CTP substrates, and all-aluminum cans. Automobile aluminum sheets can be divided into two categories: ABS is a special type; the other type is a general-purpose board, which means all the strips except ABS, there are thin plates and thick plates, and its performance requirements are lower than ABS.

Strict environmental regulations force the car to be lightweight

The accumulation of greenhouse gases on the earth and the human living environment are severely challenged. One of the main manufacturers of environmental degradation is the exhaust gas emitted by automobiles. In order to protect the environment, since the end of the last century, governments and some organizations have frequently made moves. The EU requires that cars sold in its member countries should reach 90g CO2/km in 2020, and the fuel consumption in 2016 should not exceed 4.5L/(100km). When driving on a city standard road, the car's own quality consumes about 84% of the fuel, and the fuel consumed by the passengers and the trunk is only about 15%. Known as the "country on the wheel", the new federal law of the United States stipulates that the fuel consumption of a car in 2016 must reach 7.6L / (100km), and in 2025 it should be reduced to 4.5L / (100km). Japan stipulates that the fuel consumption of small cars in 2015 should be ≤5.5L/(100km), and the CO2 emissions in 2015 must be 29% lower than that in 2010. At present, 85% of China's gasoline is consumed by various automobiles. 75% of the harmful gases in large cities are emitted by automobiles. The external dependence of PetroChina has exceeded 56.5% in 2011, and China faces an extremely severe resource situation.

This shows how important the role of vehicle lightweighting in energy conservation and emission reduction. The measures for lightweight vehicles are designed, processed and manufactured, but in today's conditions, the first two aspects of "oil and water" are not large, and the replacement of steel with low-density lightweight materials is the most Realistic choices are available in lightweight materials such as aluminum, magnesium, titanium, plastics, and composite materials, but it is most desirable to replace steel with aluminum for a long time to come, and to have the highest price/performance ratio.

Foreign ABS project construction is surging
