The invention discloses a cast aluminum silicon alloy controlling sample preparation method which comprises the following steps of S1, design of aluminum alloy components; S2, smelting and casting: adding furnace burdens in a crucible resistance furnace according to a ratio, performing smelting and refining, and pouring product in a water-cooled copper die to prepare a controlling sample after thehydrogen content is measured and the components are qualified; S3, analyzing and inspecting: after inspecting macrostructures, microstructures and fractographs, selecting a controlling sample after initial inspection is passed, and performing sawing and surface scaling; S4, after performing homogenization treatment, analyzing component the uniformity and the stability of the components, and determining a fixed value of the controlling sample; and S5, performing finish turning on the surface of the controlling sample, and processing the controlling into a finished controlling sample product. By adopting the cast alumi
