Aluminum trains are light in weight, corrosion resistant and have good running performance. The aluminum plate is mainly used in the rail car, such as the outer plate, the roof board, the floor, the interior decoration board and so on. At the same time, some small specifications of the aluminum tube are also used for the ventilation and transmission of the body. South South aluminum has the advantages of high strength, good extrudability, good weldability and good corrosion resistance for the aluminum alloy medium and thick plate produced by rail transportation. It is especially suitable for use as an aluminum train body, bottom frame and frame. It can reduce the weight of the body while ensuring the strength of the body, save energy and reduce the cost of operation and maintenance.

  Chromium bronze, at normal temperature and high temperature (400 C) has high strength and hardness, good conductivity and thermal conductivity, wear resistance and wear reduction is also very good, after aging hardening treatment, strength, hardness, conductivity and thermal conductivity are significantly improved, easy to weld and brazing, in the atmosphere and fresh water has good corrosion resistance, high It has good oxidation resistance and can handle pressure processing well in cold and hot states, but its disadvantage is that it is sensitive to the notch and causes stress concentration at the gap and sharp corner. It is easy to cause mechanical damage. Therefore, it is not suitable to be used as a flow sheet. It can be used to make electrode of electric welding machine, motor rectifying film and other parts working at high temperature, which require some strong, hardness, electrical and thermal conductivity at high temperature, and can be used in the form of brake disc and disc in the form of double

  Phosphorus deoxidizing copper has good heat conduction, corrosion resistance and excellent processability. It is easy to bear fine punching, stretching, crystal riveting, extrusion, winding, deep drawing, hot forging and welding. They are often used as gasoline or gas delivery pipes, drainage pipes, condensing pipes, mine tubes, condensers, evaporators, heat exchangers, and train box parts.
