The application discloses a low-density corrosion-resistant thin-gauge high-aluminum medium-manganese steel, and chemical components and mass percentages of the low-density corrosion-resistant thin-gauge high-aluminum medium-manganese steel include the following: C: 0.1-0.4%, Mn: 3-12%, Al: 2-5%, and the balance of Fe and inevitable impurities. The application has the advantages that a stirring friction processing method is used to introduce a microstructure feature of a phase and a grain size in a matrix in a gradient distribution into the medium-manganese steel, so that the surface modification purpose is achieved, and then the corrosion resistance is effectively improved.
