The invention provides an aluminum alloy battery cover, a preparation method thereof, and an electronic device, wherein the preparation method includes: sequentially performing hot rolling and cold rolling on an aluminum alloy ingot to obtain an aluminum alloy plate with a deformed texture inside; Recrystallization annealing is carried out on the aluminum alloy plate obtained after the annealing; the aluminum alloy battery cover is obtained by processing, decorating and post-processing the aluminum alloy plate obtained after the annealing. In the preparation method of the aluminum alloy battery cover provided by the present invention, by increasing the annealing temperature after rolling, the annealing process is changed from stress relief annealing to recrystallization annealing, thereby achieving the effect of refining the grains, and after the grains are refined , the quantity and size of the deformed texture inside the aluminum alloy plate will be reduced, so the material texture defect of the final aluminum alloy battery cover can be improved, and the surface smoothness and aesthetics of the product can be improved.
Description
technical field [0001] The invention relates to the technical field of mobile phone accessories, in particular to an aluminum alloy battery cover and a preparation method thereof, and a mobile phone including the aluminum alloy battery cover.
