Abstract
The invention discloses a preparation method of a copper-nickel-tin alloy, and the preparation method comprises the following steps of smelting and casting, solutionizing, rough rolling, annealing, cold rolling, aging, cold rolling and other processes. In the preparation method of the copper-nickel-tin alloy disclosed by the invention, homogenization treatment is not carried out between the smelting and rough rolling, and the high-temperature short-time solid solution heat treatment is directly carried out, so that the Sn-rich phase in the alloy can be solutionized in a copper matrix, the brittle phase NixSny generated in the casting process is eliminated and the alloy has excellent plastic processing performance, thereby facilitating the subsequent processing. In addition, the rough rolling is directly carried out after the solid solution treatment, and homogenization treatment and hot rolling processes in the existing preparation methods are omitted, thus saving energy, shortening the process, improving production efficiency and lowering production cost.
