The Application of Aluminum Alloy Profiles in High-speed Railway Transportation-Aluminum Profiles SUPPLIER

Generally speaking, aluminum alloy profiles are widely used in the manufacturing of various vehicles and rail vehicles. They are not only used for the body of rail vehicles, but also for other structures, such as doors, windows and furniture. The increasing application of these alloys in railway manufacturing has become a major topic of railway transportation modernization. The most common use of these materials is to produce large -scale extrusion profiles, such as profiles used to manufacture rail vehicles. The squeezing material is made of aluminum alloy material, which has excellent strength, weight reduction and corrosion resistance. These materials are also suitable for various surface treatment methods. The use of aluminum alloy in high -speed railway transportation is an ideal method to reduce the net weight of railway passenger cars. It is 30%to 50%lighter than steel, which saves fuel and reduces carbon dioxide emissions. These parts are also easy to replace, and the maintenance volume is less. Customized according to customer requirements. These materials are also very easy to process. They can make large -scale extrusion profiles, which are ideal choices for light railway vehicles. They have excellent corrosion resistance and formability. These profiles can meet the growing demand for light products in the automotive and railway transportation industry. The extrusion process includes mold heating, break, online quenching and stretching. The production process includes a series of stages, which have different degrees of effect on the performance of aluminum alloy at this stage. The most important factor affecting the curved material curvature is the eccentricity of the mold hole. During the squeezing process, the starting point of the curved curve should be as close to the support as much as possible. This will avoid the distortion of symmetry and asymmetric cross section. The starting point should also be as close as possible to the exit of the extruded mold.

By changing the squeezing temperature, it can further improve the curvature of aluminum alloy. The curved contour is highly rigid and has excellent air dynamic performance. In order to meet the needs of porous thin wall hollow profiles, the squeezing process of aluminum alloy has been developed.

The 6000 series alloys are very suitable for welding structure and have perfect squeezing formability. They have high corrosion, good strength and moderate flexibility. The typical aluminum alloy is 5000 and 7000 series.

The 5000 series alloy has the highest strength. The 7000 series alloy has medium strength and is very suitable for welding structure. They are widely used in the production of high -speed railways. They have excellent corrosion resistance and are used for 300 new trunk high -speed trains. Aluminum alloy profiles can be made through porous molds. Wing -type mold supports the side of the workpiece to prevent the workpiece from collapse. The position of the wing rotation center affects the sliding direction of the workpiece on the mold. This method is used to produce a curved hollow rectangular aluminum profile with flange.
