description The invention belongs to the technical field of aluminum alloy material preparation, and discloses a medium-high voltage electronic aluminum foil for an aluminum electrolytic capacitor and a preparation method thereof. The method comprises the following steps: putting an aluminum ingot and an aluminum intermediate alloy into a smelting furnace, heating and melting to obtain molten aluminum, preserving heat, refining, standing, casting, sawing, milling, homogenizing annealing, hot rolling, cold rolling, rewinding and trimming, cold rolling, foil rolling, intermediate annealing, foil rolling, cleaning, shearing and coil-dividing, and annealing a finished product to obtain the medium-high voltage electronic aluminum foil for the aluminum electrolytic capacitor. According to the method, on the basis of an existing production process of the middle-high voltage electronic aluminum foil, the number of hot rolling process passes is reduced, the average pass reduction rate is increased, namely, the number of hot rolli
