Abstract

The invention discloses a method for preparing a high-strength and high-conductivity copper alloy wire for an automotive electric wire and cable. The copper alloy wire comprises the following component elements in percentage by weight: 1.5-2.5% of Zn, 0.8-1.6% of Cr, 0.5-1.0% of Ni, 0.3-0.6% of Mn, 0.25-0.35% of Ag, 0.1-0.2% of Ti, 0.04-0.08% of Nb, 0.03-0.05% of Sb, 0.015-0.025% of B, 0.005-0.015% of Te, 0.03-0.04% of Ce, 0.02-0.03% of Tm, 0.005-0.01% of S, 0.003-0.005% of P and the balance of copper and inevitable impurities. By virtue of the method disclosed by the invention, the mechanical strength of the copper alloy wire can be greatly improved while the excellent electrical conductivity is maintained, and the problem of the contradiction between the mechanical strength and electrical conductivity of the copper alloy wire is effectively solved; the method has the advantages of rapid preparation, simple process, environment friendliness, low cost, high efficiency and convenience in control, and the automatic mass production can be achieved.

Description

technical field [0001] The invention relates to a method for preparing high-strength and high-conductivity copper alloy wires for automobile wires and 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, the strength and conductivity of existing copper alloy wires are often inversely proportional to each other, which affects their performance. Therefore, it is urgent to develop high-strength and high-conductivity copper alloy wires to meet market demand. Contents of the invention [0003] In order to solve the problem of conflicting mechanical strength and electrical conductivity of existing copper alloy...
