The invention discloses a method for preparing an aluminum-based medium-entropy alloy through electromagnetic stirring casting, and relates to the technical field of high-performance metal material manufacturing. The method comprises the steps of alloy preparation, mold drying, charging, furnace burden melting, molten aluminum refining, casting and demolding. According to the method, aluminum alloy melt in a casting mold is stirred through an electromagnetic field, the electromagnetic field belongs to a non-contact external energy field, primary dendrites can be effectively smashed, as-cast structures are remarkably refined, and the segregation tendency of alloy elements in the solidification process is improved. The electromagnetic stirring casting of the aluminum-based medium-entropy alloy is implemented through traditional liquid solidification forming, the preparation process is simple in flow, a large-specification high-quality casting blank can be prepared, and good application prospects are achieved.
