A die-cast aluminum alloy material, a preparation method therefor, and a use thereof. The die-cast aluminum alloy material comprises the following by weight: 8.0%-11.0% silicon, less than 0.5% iron, 1.0%-3.0% copper, 0.5%-2.5% magnesium, 0.5%-1.2% manganese, less than 1.3% zinc, 0.08%-0.15% titanium, 0.1%-0.2% zirconium, 0.02%-0.04% strontium and less than 1.0% impurities, the mass ratio of copper to magnesium being (0.5-2.0):1. The die-cast aluminum alloy material can obtain high mechanical properties, especially high yield strength, without heat treatment, while also having high corrosion resistance. In addition, said material can meet the requirements of high yield strength and high toughness and corrosion resistance for parts such as motor housings of new energy vehicles.
