The application discloses a lightweight all-aluminum alloy powder and particle material transportation semitrailer, which comprises a tank assembly which is made of an all-aluminum alloy part; the bottom part of the tank assembly is fixedly connected with a frame assembly; the frame assembly is made of the all-aluminum alloy part; two heaviest components of the semitrailer are the tank assembly and the frame assembly, and account for about 90 percent of total weight; after the all-aluminum alloy parts are adopted by both the tank assembly and the frame assembly, the total weight is reduced by one half in comparison with the weight of an all-stainless steel semitrailer in the prior art, and is reduced by 1/3 in comparison with the weight of a semi-stainless steel and semi-aluminum alloy semitrailer; as a body is lighter, the tank can be made bigger after the own weight of the semitrailer is reduced, and more materials can be loaded by the semitrailer at one time; the tank assembly and the frame assembly are respectively made of the all-aluminum alloy part, and the tank assembly can be directly welded to the frame assembly, so the problems that a subframe needs to be designed and the tank assembly and the frame assembly can be connected only by a bolt as two kinds of materials are adopted are avoided, and a body structure is simple, manufacturing processes are simplified, and the total weight is lighter.
