5083 aluminum alloy has strong corrosion resistance. A dense oxide film is easily formed on the surface of aluminum alloy. It has good resistance to oxygen in the atmosphere. Therefore, aluminum alloy has better corrosion resistance than steel car bodies. Especially the parts of the car body that are not easy to coat. At the same time, the aluminum alloy surface can be chemically colored, painted, and sprayed. Using these methods can further improve the corrosion resistance of aluminum structural parts. In addition to the high corrosion resistance of subway light rail materials , It also makes the weight of the vehicle further realized, and the energy consumption of the vehicle is reduced, the maintenance cost is reduced, and the aluminum profile can be 100% recycled, which can reduce energy consumption.
In summary, aluminum alloy has excellent fire resistance and arc resistance, its melting point is lower than that of steel, excellent heat dissipation and strong corrosion resistance, and also has excellent plasticity. With the development of aluminum alloy welding technology With continuous progress, the manufacturing technology of aluminum alloy vehicles is becoming more and more mature, and aluminum alloy parts are easy to replace, without rust removal, suitable for various surface treatments, can be recycled and reused, and save resources. Therefore, the use of Mingtai 5083 aluminum plate welding for subway light rail materials is more suitable.
