The invention provides a high-elongation-rate heat-resistant aluminum alloy suitable for gravity casting and a preparation method thereof. The alloy comprises the following elements of, by weight, 9.0-12.0% of Si, 0.05-0.4% of Cu, 0.02-0.05% of Mg, 0.05-0.1% of Sc, 0.6-0.8% of M and and the balance Al and inevitable Fe impurities, wherein the M comprises at least two elements of Ti, Zr and V. After gravity casting of the high-elongation-rate heat-resistant aluminum alloy suitable for gravity casting, room-temperature yield strength of the as-cast alloy can reach 143-152MPa, the elongation ratecan reach 8.0%-12.0%, high-temperature tensile strength at 200 DEG C can reach 158-170MPa, the high-temperature elongation rate can reach 10.0%-20.0%, the room-temperature yield strength and heat resistance are excellent, the alloy can be applied to automobile parts without solid solution heat treatment, so that the requirements of light-weight development of automobiles can be met.
