In order to further improve the overall performance or part of the performance of the 6061 aluminum alloy, the components of the aluminum alloy are required to be adjusted or the processing technology is required to be improved, so that the aluminum alloy profile with the required performance is obtained. The patent with publication number of CN113355569A discloses a 6-series aluminum alloy section bar suitable for an aluminum template and a preparation method thereof, and the patent comprises the following steps: by adjusting the alloy components of the aluminum alloy cast ingot and the heat treatment process, the average main cylinder pressure of the extrusion process of the 6-series aluminum alloy section suitable for the aluminum template is effectively reduced, and the finally prepared aluminum template section has more excellent tensile strength and yield strength. In addition, the surface of the homogenized aluminum alloy cast ingot is subjected to surface brushing or peeling treatment, so that the influence on the strength and corrosion resistance of the profile caused by the fact that impurities in a surface segregation layer are involved in the extrusion process is avoided as much as possible; however, the peeling operation increases the production cost, and the problem of recrystallization occurs because the processing strain becomes the driving force in the extrusion molding stage, and the recrystallization, particularly the coarse recrystallization, can lead to the reduction of the corrosion resistance, so the corrosion resistance of the 6-series aluminum alloy section prepared by the method can be only equal to or even slightly worse than that of the conventional 6061 aluminum alloy.
