A method for preparing high-toughness heat-resistant aluminum alloy armature material, comprises: heating and melting an aluminum ingot into an aluminum liquid; adding the following elements to the aluminum solution in mass percent: Ce 6-12%, Y 5-9.5%, Zr 0.5-3%, Mg 0.1-2.5%, X 0.15-2.5%, Fe 0.15-0.25%, Mn 0.05-0.15%, and Si 0.1-0.5%; forming an alloy solution and casting same into an alloy ingot; processing the alloy ingot into spherical alloy powder; subjecting the spherical alloy powder to selective laser melting and solidification forming to produce nano-scale AlCe, Al(Y, Zr), and/or AlX intermetallic compounds distributed in a net-like skeleton structure in an aluminum matrix. The material of the present disclosure has low density, high-temperature resistance, high energy absorption rate and excellent electrical conductivity, and excellent mechanical properties at room temperature and high temperature.
