In the current manufacture and maintenance of rail car bodies, there are alloys such as 5052, 5083, 5454, 6061, etc. The extruded profiles are 5083, 6061, 7N01, etc., and some new alloys such as 5059, 5383, 6082, etc. Also have some applications. They all have good solderability, the wire is 5356 or 5556 alloy, of course * is the use of friction stir welding (FSW), not only high welding quality, but also no welding wire. Later, the 7N01 alloy developed in Japan (Mn0.20~0.7, Mg1.0~2.0, Zn4.0~5.0, unit%) was widely used in the manufacture of rail vehicles; Germany used 5005 alloy plate in the manufacture of high-speed rail Trans Rapid cars. The siding was made, and the profiles used were extruded with 6061, 6063, and 6005 alloys. In short, until now, whether in China or other countries to manufacture high-speed rail vehicles, these alloys are still basically used.
