This invention relates to the field of alloy materials technology, specifically to a method for preparing nickel-chromium-silicon-manganese alloy foil, comprising the following steps: S1: alloy ingot preparation; S2: hot-rolled slab preparation; S3: preliminary foil preparation; S4: nickel-chromium-silicon-manganese alloy foil preparation. In this invention, by rationally combining nickel, chromium, silicon, and manganese, nickel and chromium form a stable nickel-chromium solid solution to solidify the foundation against high-temperature oxidation; silicon combines with oxygen to form a dense silicon oxide protective film; manganese synergistically refines the oxide film structure to reduce film cracking; combined with the effects of titanium, zirconium, hafnium, and composite powder in the composite additives, both the adhesion between the oxide film and the substrate is enhanced, and the oxide film peeling off at high temperatures is inhibited. The erbium and nano-silicon carbide in the pretreated composite powder further improve the stability of the oxide film, synergistically delaying the high-temperature oxidation rate with the alloy base components, effectively improving the high-temperature oxidation resistance of the alloy foil and extending its service life under high-temperature conditions.
