Abstract

The invention discloses a preparation method of copper-chrome alloy, and belongs to the technical field of the preparation of alloy material. In the method, 55% CuO, Cr2O3 and aluminum powder are taken as main raw materials. The preparation method comprises the following steps of: adding MgSO4 and CaF2; adopting a material laminated self-propagating reaction technology, wherein A layer is the mixed materials of CuO, Cr2O3, aluminum powder and CaF2 and the mixed materials are added on the bottom layer of a reaction mould, B layer is the mixture of MgSO4, Al and CaF2 and the mixture is added on the A layer materials, and an igniting agent is added on the B layer material; and adopting an aluminothermic reducing method to obtain copper-chrome (Cu-Cr) alloy. According to the preparation method, the raw material source is wide, the production cost is low, the operation method is simple, and the product quality is greatly improved.
