Preparation method for high-strength wear-resistant alloy Cu-15Ni-8Sn

The invention discloses a preparation method for a high-strength wear-resistant alloy Cu-15Ni-8Sn. The process comprises the following steps: adding electrolytic copper and nickel; pouring the electrolytic copper and nickel in an intermediate-frequency coreless induction furnace; adding charcoal; charging nitrogen gas with one barometric pressure; melting; melting for 30-65 minutes at 1300-1350 DEG C; adding tin and melting at 1250-1300 DEG C; adding a refiner and a deoxidizer; stirring; adding a grain refiner; adding a modifier; slagging off; carrying out inspection before melting; carrying out electromagnetic casting after ingredients are qualified; cutting a head and a tail; scalping; carrying out ingredient inspection after melting; carrying out organization structure analysis; and carrying out performance detection. A Cu-15Ni-8SnC72900 alloy melt and cast by virtue of the intermediate-frequency coreless induction furnace, which is obtained by the preparation method disclosed by the invention, is low in production cost; and the developed products are high in quality. The developed products can be applied to national defense and military industry, ocean engineering and high-end preparation manufacturing industry; and the increasingly urgent needs of the national defense and military industry, ocean engineering and high-end preparation manufacturing industry on high-performance copper alloy materials are met.
