More Information
Summary:The invention relates to a preparation method of a copper-nickel-tin alloy, which comprises the following steps: step 1, raw material preparation: preparing copper, nickel and tin raw materials according to a corresponding mass ratio, and cleaning and drying the raw materials; 2, according to the required alloy proportion, copper, nickel and tin raw materials are placed according to the mass proportion; thirdly, the raw materials are smashed, and the copper raw materials, the nickel raw materials and the tin raw materials are smashed into particles for use; 4, melting the alloy; 5, secondary smashing is conducted, specifically, the temperature of the smelting furnace is lowered to 200 DEG C, the tin component in the alloy is softened, and the alloy is smashed into particles; and step 6, forming: continuously heating the crushed granules in a smelting furnace until the molten alloy granules are in a liquid state, adding phosphorus and antimony powder into the molten alloy granules, and cooling the liquid to ob
