Embodiment Construction

[0015] (1) Put the copper block into the smelting furnace and raise the temperature to 1180°C to melt, then raise the temperature to 1250°C, add the relevant alloy ingredients, stir evenly, after it is completely melted, adjust the temperature to 1200°C and add refining agent to refine for 30 minutes, then grill After holding the slag for 20 minutes; then conduct a rapid chemical analysis of the copper alloy liquid before the furnace, so that the weight percentage of each element in the copper alloy liquid meets the following requirements: Fe 0.3-0.5, Al 0.2-0.3, Sn 0.4-0.6, Cr 0.2- 0.4, Ni 0.1-0.2, Be 0.15-0.25, Mo 0.06-0.12, Nd 0.06-0.09, Ta 0.04-0.08, Zr 0.03-0.06, P 0.02-0.03, the balance is copper and unavoidable impurities; Adjust the weight percentage of each component in the formula to feed;

[0016] (2) Put the Mn-Co-Ge-Ga alloy block into the furnace according to 0.2% of the weight of the copper block and melt it. The mass ratio of Zr, Cu, Ti, and La elements in th...

Abstract

The invention discloses a preparation method of a high-strength copper alloy wire for an automobile industry. The high-strength copper alloy wire is composed of the flowing elements in percentage by weight: 0.3-0.5% of Fe, 0.2-0.3% of Al, 0.4-0.6% of Sn, 0.2-0.4% of Cr, 0.1-0.2% of Ni, 0.15-0.25% of Be, 0.06-0.12% of Mo, 0.06-0.09% of Nd, 0.04-0.08% of Ta, 0.03-0.06% of Zr, 0.02-0.03% of P and the balance of copper and unavoidable impurities. According to the preparation method, on the basis of ensuring the electrical conductivity and machinability of the copper alloy wire, by increasing the content of a Mg element and adding a small amount of elements such as Nd, Ta and Zr and the like, the mechanical strength of a copper alloy is improved; and the high-strength copper alloy wire has the characteristics of good wear resistance, stress corrosion resistance and high temperature resistance, low cost, good processing performance, good welding performance, and the like.

Description

technical field [0001] The invention relates to a method for preparing a high-strength copper alloy wire used in the automobile industry, and belongs to the technical field of copper alloy manufacturing. Background technique [0002] Copper alloy is an important material for the national economy. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. It is widely used in the automobile industry. However, the tensile strength of the existing copper alloy wire cannot meet the high-speed development of the automobile industry. . Therefore, there is an urgent need to develop a high-strength copper alloy wire. Contents of the invention [0003] The object of the present invention is to provide a method for preparing high-strength copper alloy wires for the automotive industry to improve the mechanical strength of the copper alloy wires in view of the deficiencies in the prior art. [0004] The technical scheme that the present inv...
