5083 aluminum sheet belong to Al-Mg-Si alloy, the use of a wide range of. The application of 5083 aluminum sheet belongs to the high-end field of aluminum processing industry. With the rapid development of domestic rail transit market and the arrival of the era of globalization, it has a huge market prospect. According to the market development of 5083 aluminum sheet and the demand of the light weight, the production of aluminum alloy sheet was increased, and the production process of aluminum alloy sheet was strictly controlled by 5083 aluminum alloy. Sure, the alloy casting process optimization, homogenization heat treatment and rolling, the 5083 aluminum sheet Haomei with aluminum performance with foreign materials, to meet user requirements, especially to meet the increasing demand of aluminum processing, rail transportation, high-grade car complex parts such as marine, very broad prospects for application.

As we all know, air reservoir is the gas storage device in automotive braking system, is used to store the gas from air compressor. Air reservoir consists of one cylinder and two shell cover. All the air reservoir are made of aluminum magnesium alloy and iron. At now, most of air reservoir  use the aluminum magnesium alloy, because aluminum magnesium alloy material naturally formed a layer of film on surface. This dense protective film protect the matrix form corrosion, it extend the service life of air reservoir and lighten the weight of car body, what’s more, aluminum magnesium alloy has a high stretching rate, and it will not easy to break.
