A method for preparing a casting material for nuclear power and wind power, comprising the following steps: placing, in percentage by mass, 5-7% of aluminium, 2-4% of iron, 0-1.2% of manganese, 10-12% of nickel, 0.5-2% of zinc and the balance of copper in a mains frequency induction furnace, heating to 1150°C until completely melted, and maintaining the temperature. In the provided material for abrasion-resistant parts for nuclear power and wind power, titanium carbide ceramic particles are added to a traditional bronze material so as to increase the hardness of the casting alloy material; and a corresponding rare earth element of lanthanum or cerium is appropriately added to further refine and improve the particle structure of the internal material of the alloy, so that the strength and hardness of the alloy material can be achieved without further forging or heat treatment of the material, so as to further satisfy the requirements of the materials for abrasion-resistant parts for nuclear power and wind pow
