The invention discloses a method for simultaneously improving intensity, ductility and abrasion resistance of copper-tin alloys, and belongs to the technical field of material preparation. The methodcomprises the steps of preparing raw materials of 8-15% of Sn,1-8% of Fe, 0.8-1.2% of P, and the balance Cu, placing the raw materials in a medium frequency induction heating furnace, performing heating for melting, then treating molten mass by a quick cooling method, controlling the cooling rate and the supercooling degree of the molten mass, and adjusting and controlling the proportion of nanoscale iron enriched phases and intercrystalline micron order iron enriched phases in a primary phase. The intensity and the ductility of the alloys are reinforced by using the nanoscale iron enriched phase, the abrasion resistance of the alloys is improved by an intercrystalline micron order iron enriched phase, and through controlling the proportion of the nanoscale iron enriched phase to the micron order iron enriched phase, high-strength high-ductility high-wear-resistance copper-tin alloys are obtained. The alloys are simple in components, the preparation technology is short in technologicalprocesses, the method is low in cost, castings are good in properties, and the method is suitable for fields of high speed rails, heavy trucks, aerospace and the like, and has favorable application prospects.
