Problems solved by technology

With the increase of Fe content, the Cu-Fe alloy is easy to form a structure with severe segregation during solidification, that is, the microstructure of the alloy mainly exists in the form of primary Fe-rich dendrites in the Cu matrix. The higher the Fe content, the α -The thicker the Fe dendrite, because of this characteristic of the alloy, it greatly hinders the production and application of Cu-Fe alloy

Abstract

The invention discloses a Cu-Fe alloy wire and a preparing method thereof, and belongs to the technical field of non-ferrous alloy. The preparing method includes the steps that an intermediate alloy with even ingredients is used as parent materials, wherein the ingredients of the parent materials comprise 45% to 60% of Fe, 0.20% to 0.35% of Ni, not smaller than 0% of RE and the balance Cu; and then cathode copper and the intermediate alloy parent materials serve as raw materials, and a casting-state alloy ingot is obtained through vacuum melting and further machined into the Cu-Fe alloy wire, wherein the wire is prepared from 8.0% to 13.0% of Fe and the balance Cu and unavoidable impurities. When the prepared Cu-Fe alloy is in the casting state and the forging state, Fe-Cu solid solution is good, Fe elements are evenly distributed without segregation, and good machinability is achieved. The diameter phi of the further-machined finished wire ranges from 0.05 mm to 0.1 mm, the tensile strength of the finished wire is larger than or equal to 440 N / mm<2>, and the elongation of the finished wire is larger than or equal to 10%. The Cu-Fe alloy further has the excellent electromagnetic shielding effect.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal alloys, in particular to a copper-iron alloy wire and a preparation method thereof. Background technique [0002] Metal materials have a wide range of applications, but there are very few reports on copper-iron alloys at home and abroad. Some characteristics of Cu-Fe alloys can be predicted from the knowledge of metal materials: (1) The melting point should be higher than Cu and lower than Fe, If it is used as a vacuum electrical contact material to replace Cu alloy, its arc ablation resistance can be improved; (2) Both pure copper and pure iron have good ductility, so Cu-Fe alloy should also have this property ; (3) substituting part of Cu with Fe can reduce the cost of Cu material; (4) has electromagnetic shielding effect. [0003] figure 1 The phase diagram of the Cu-Fe binary alloy is shown. The primary solid solution theory believes that the more similar the atomic radius and elec...
