Abstract

The invention provides a high-thermal-conductivity copper iron alloy material and a preparation method and application thereof. The copper and iron alloy material comprises the following chemical components in percentage by weight: 10-30% of Fe, and the balance of Cu. The preparation method comprises the following steps: (1) burdening: corresponding raw materials are weighed in proportion; (2) smelting: the raw materials are loaded in a vacuum medium-frequency induction furnace, and are heated to 1500-1700 DEG C after loading, wherein Fe is fed by adopting a Cu-Fe intermediate alloy mode, andCu adopts an electrolytic copper plate; (3) degassing and casting: the refining, the degassing and the deoxidation are performed after the smelting; and melts are leaded down for continuous casting asingots with different specifications according to demands; and (4) molding: the ingots are prepared as products with different requirements and specifications by several different processes of forging, rolling, extrusion and drawing. The prepared CuFe alloy material is low in gas content, few in inclusion, uniform in structure component and free of macroscopic and microscopic defects as Cu and Feenrichment, and can be used as an excellent heat conducting material applied to multiple fields.

Description

technical field [0001] The invention belongs to the technical field of heat conduction material manufacturing, and in particular relates to a high heat conduction copper-iron alloy material and its preparation method and application. Background technique [0002] Copper and iron alloys have the same electrical conductivity, thermal conductivity, ductility, and elasticity as copper, and have the same properties as iron, such as wear resistance, tensile strength, hardness, and magnetism, and their comprehensive properties are excellent. Iron and copper are the most abundant on the earth, and there is no harmful substance in the reuse of alloys, which has attracted a lot of attention and research in the world. However, the phase difference between copper and iron is large. If the iron content is less than 2.5% and forms an alloy through solid solution, if the iron content is more than 3%, the alloy does not undergo solid solution and segregation occurs, so it is difficult to us...
