The invention provides a special-shaped aluminum-based cavity and a preparation method and application thereof, and belongs to the field of high-entropy alloys. Comprising a special-shaped aluminum-based cavity base body and a high-entropy alloy coating deposited on the surface of the special-shaped aluminum-based cavity base body, the high-entropy alloy coating comprises a connecting layer, a high-entropy diffusion blocking layer and a high-entropy anti-oxidation layer which are sequentially arranged in a stacked mode, the connecting layer makes contact with the special-shaped aluminum-based cavity base body, and the high-entropy diffusion blocking layer makes contact with the high-entropy anti-oxidation layer. And the high-entropy alloy coating contains not less than five types of elements. The metal coating is a non-traditional copper film, the high-entropy alloy coating can enhance the welding performance and solve the surface oxidation performance caused by long-time storage, and meanwhile, the high-entr
