Abstract

The invention relates to the technical field of alloys, in particular to a copper-iron alloy and a preparation method thereof. The preparation method comprises the following steps that 1, raw material copper is refined, specifically, copper ore is subjected to air calcination, then a reducing agent is added for continuous calcination to obtain crude copper, and then wet copper extraction, crude copper leaching (leaching liquid), extraction, reverse extraction and electrodeposition are carried out to obtain electrolytic copper. According to the copper-iron alloy and the preparation method thereof, copper with high purity is obtained through cooperation of a calcination method and wet-process copper extraction, iron is obtained through high-temperature calcination, limestone can effectively absorb harmful gas generated during iron refining, copper-iron powder prepared through a high-pressure water atomization method is uniform in particle size, and does not influence components of copper and iron, the purity of the copper-iron alloy is guaranteed, and a V-shaped mixer is adopted for powder mixing and proportioning so that iron powder can be evenly mixed into copper powder, the uniformity of a precipitated phase of a finished product is improved, and the compactness of the copper-iron alloy can be improved by alternately conducting aging treatment and deformation machining treatment.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a copper-iron alloy and a preparation method thereof. Background technique [0002] An alloy is a mixture of two or more chemical substances (at least one of which is a metal) with metallic properties. Generally, the components are fused into a uniform liquid and then condensed. The alloy of the solid solution is slightly The structure has a single phase, and the alloy that is partly a solution has two or more phases, and its distribution may be homogeneous or not. It depends on the temperature change during the cooling process of the material. Generally, there will be a kind of intermetallic compound. Alloy or pure metal is wrapped in another pure metal. The melting temperature of copper and iron is not much different, both are around 1200 degrees. They are completely compatible to form copper-iron alloy, and have excellent electrical conductivity, thermal conductivity and ductil...
