Each trademark has its own characteristics, which are applicable to the different places of the automobile platform. 5 series alloy is used in the automobile platform. There are many kinds of automobile lightweight mistakes, the most important and most common skill is to accept lightweight materials. Among many materials, aluminum is the most widely used lightweight material. The density of aluminum is about 1 / 3 of that of steel, which is characterized by high strength, corrosion resistance, good thermosetting property, easy forming, re acquisition, etc. it is also an ideal metal material for the automobile industry with mature technology. 5-series aluminum alloy in aluminum alloy is also called magnesium aluminum alloy. At present, the amount of alloy used in automobile platform is relatively large.
Magnesium content accounts for 6% of the total quality. It can effectively reduce the hardness and strength of products, thus making products easier to process. The hardness of 5052 alloy aluminum plate is greater than that of 3-Series alloy, and it has strong plasticity and the strongest corrosion resistance. In addition, the corrosion resistance of 5052 alloy aluminum plate is much better than that of other alloys in the sea water or in the atmosphere. 5 series alloys are used in the alloy series of rail transit platform, and their alloy trademarks are mainly 5005, 5042, 5052, 5083, 5086, 5754, 5182 and 5251. The products are mainly used for rail car body, transport vehicles, ships, automobiles, equipment decoration, electronic and electrical platforms.
Automobile lightweight is the direction of the development of modern automobile industry technology. A few aluminum tycoons have opened an all-round alliance with CSR in the aspects of rail transit plates, large section aluminum profiles, railcar welding, construction of rail transit passenger transport equipment manufacturing and repair base, etc. At present, although the aluminum alloy trailer is no longer a fresh thing in China, its market share is very small. The first aluminum alloy Trailer in China started to appear at the 2008 Taiyuan truck industry exhibition, which was developed and produced by Baotou Yuli industry. So far, but in a few years, it has not been widely used. However, both the transportation industry and the trailer production industry feel that the lighter 5052 alloy aluminum plate trailer is bound to replace the steel trailer and become the mainstream of the market in the future.
