In order to reduce energy consumption and increase operating speed, lightweight car bodies have always been the direction of rail transit vehicle technology research and development. For this reason, the selection of suitable materials is essential for lightweight car bodies. Aluminium pipe fitting materials have become the first choice for new rail transit vehicle body materials due to the advantages of low density, moderate strength, and easy forming.
Aluminum structural pipe fittings in Rail
The aluminum alloy used in rail transit car bodies is mainly made of profiles, supplemented by plates, and forgings are used for a small number of parts.
At present, the main aluminum alloys used in rail transit car bodies are 5 series, 6 series and 7 series. The most used Aluminium tube fitting profiles are 6 series aluminum alloys, and most of them are 6005A and 6082 aluminum alloys. The excellent extrusion performance of aluminum alloy has laid a good foundation for the large-scale use of aluminum profiles, and the domestic mature and stable extrusion manufacturing capabilities have boosted the application of aluminum profiles [1]. The use of large hollow aluminum profiles simplifies the manufacturing process of the car body
