[0002] Aluminum profiles are a special-shaped metal material made of aluminum alloy through processing methods such as extrusion or rolling, and are widely used in rail transit. With the continuous development and popularization of rail transit technology, the application of aluminum profiles in the field of rail transit will be more extensive and in-depth. Especially in the context of the rapid development of urban rail transit network construction, the demand for aluminum profiles will continue to grow. At the same time, with the continuous progress of technology and the innovation of materials, the performance of aluminum profiles will also be continuously improved, providing strong support for the safety, efficiency and sustainable development of rail transit.
