Embodiment approach

[0018] According to a preferred embodiment of the present invention, the copper alloy material further includes 0.001-0.02% Ag by weight percentage. Because Ag has excellent electrical conductivity, the role of Ag in copper alloys is mainly to increase electrical conductivity. It can be seen that the present invention uses industrial pure copper as a matrix, and is compounded by adding an appropriate amount of La, Y, Te, Zr and Ag elements. Copper alloy materials with high strength, high toughness and high electrical conductivity. In addition to silver, the copper alloy material of the present invention inevitably includes some impurities, such as iron, bismuth, tin, arsenic, niobium, etc., and the total content of these impurities is less than 0.01%.

[0019] The composite addition of La, Y, Te and Zr elements within a certain range can make the copper material have higher mechanical properties and excellent electrical conductivity, and significantly improve the tensile stren...

[0028] The weight percentage of each component in the copper alloy raw material is shown in Table 1, wherein the purity of La and Y is 99-99.9%, the purity of Te, Zr and Ag is 99.9-99.99%, and copper is general industrial pure copper and unavoidable Impurities. The preparation process is as follows: Weigh pure copper and La, Y, Te, Zr and other elements according to the formula in Table 1, and combine two or more to prepare Cu-Te, Cu-Zr, Cu-La, Cu-Y or Cu -Zr-Te, Cu-Y-La master alloy, weigh pure copper and master alloy, use ZG-10B vacuum induction melting furnace for melting and casting, casting power 25-30KW, time 25 minutes, refining for 5 minutes, cooling to pouring temperature Post quick pour. Copper alloy ingots were prepared by the above-mentioned process, and the surface impurities and defects of the copper ingots were removed by car, and then placed in an electric furnace at 835°C for 1 hour, the extrusion mold was kept at 550°C, and a 300-ton vertical hydraulic press...

Abstract

The invention discloses a copper alloy material, a preparation method thereof and a copper lead prepared thereby. The copper alloy material comprises the following components by weight: 0.02 to 0.72 percent of rare earth element and the balance of Cu. The copper alloy material with excellent comprehensive performance, such as high strength, high toughness and high conductivity, is obtained by adopting a rare earth element composite copper material, so that the using requirements of the copper lead on high strength and high conductivity are met, and the copper alloy material can be widely applied to other parts.

Description

technical field [0001] The invention relates to the technical field of alloy preparation, in particular to a copper alloy material, a preparation method thereof and a copper wire prepared therefrom. Background technique [0002] Pure copper wire has excellent electrical conductivity, corrosion resistance and process performance, and can be widely used in wires for electrical equipment, communication cables, electromagnetic wires and high-fidelity wires. However, with the progress of society, pure copper wires are less and less able to meet the needs of industrial development due to their low strength and the strengthening effect is easy to disappear when heated. Therefore, there is an urgent need for a new type of high-strength and high-conductivity copper wire to replace the current pure copper wire. Contents of the invention [0003] The invention aims to provide a copper alloy material, a preparation method thereof and a copper wire prepared therefrom. The copper alloy...
