Embodiment Construction

[0013] A method for preparing high-strength and tough copper alloy wires for automotive cables, comprising the following steps:

[0014] (1) Put the copper block into the melting furnace and raise the temperature to 1240°C to melt, then raise the temperature to 1280°C, add the relevant alloy ingredients, stir evenly, after all the melting, adjust the temperature to 1250°C and add refining agent to refine for 30 minutes, then grill After slag, heat preservation for 18 minutes; and 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: Al 4.0-6.0, Mn 1.5-2.5, Fe 1.2-1.8, Ni 0.6- 1.4, Be 0.5-1.0, Sn 0.3-0.6, Co 0.25-0.45, V 0.1-0.2, Sr 0.008-0.016, Se 0.005-0.015, La 0.03-0.04, Y 0.02-0.03, Pr 0.01-0.02, P 0.005- 0.01, the balance is copper and unavoidable impurities; after analysis, adjust the feed according to the weight percentage of each c...

Abstract

The invention discloses a preparation method of a high-strength high-toughness copper alloy wire for automatic cables. The copper alloy wire comprises the following components by weight percent: 4.0%-6.0% of Al, 1.5%-2.5% of Mn, 1.2%-1.8% of Fe, 0.6%-1.4% of Ni, 0.5%-1.0% of Be, 0.3%-0.6% of Sn, 0.25%-0.45% of Co, 0.1%-0.2% of V, 0.008%-0.016% of Sr, 0.005%-0.015% of Se, 0.03%-0.04% of La, 0.02%-0.03% of Y, 0.01%-0.02% of Pr, 0.005%-0.01% of P and the balance of copper and inevitable impurities. According to the method, the mechanical strength of the copper alloy wire can be greatly enhanced, the ductility of the copper alloy wire is remarkably improved, excellent toughness and plasticity can be kept, and the conflict between the mechanical strength and the toughness of the copper alloy wire is effectively eliminated; meanwhile, the method is simple in production process, low in cost, high in efficiency and easy to control, can achieve large-scale automated production, and has good industrial prospect.

Description

technical field [0001] The invention relates to a method for preparing high-strength and tough copper alloy wires for automobile cables, belonging to the technical field of copper alloy manufacturing. Background technique [0002] Copper alloy wire has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance, and is widely used in automotive wires and cables. In recent years, with the rapid development of the automobile industry, higher requirements have been placed on the performance of copper alloy wires. However, existing copper alloy wires have a trade-off between toughness and mechanical strength, which leads to high-strength copper alloy wires prone to wrinkles and cracks during use, which affects their performance. Therefore, it is urgent to develop high-strength and tough copper alloys. line to meet market demand. Contents of the invention [0003] The object of the present invention is to provide a method for preparing high-st...
