Embodiment Construction

[0008] Preferred embodiments of the present invention are described below. The preferred preparation method of the ultra-high tension copper wire of the present invention comprises steps:

[0009] (1) Melting and continuous casting of Cu-Al alloy

[0010] Melt electrolytic copper in an induction furnace at a melting temperature of 1150-1250°C, and cover the melt with roasted charcoal to prepare a Cu-Al alloy, wherein the Al content is 0.1-0.63wt%, and the balance is copper (so that the final Cu -Al 2 o 3 Al in alloy 2 o 3 The content is basically 0.2-1.2wt%), and the Cu-Al alloy melt is formed after melting, and the Cu-Al master alloy rod of Φ8mm-Φ25mm is produced by the upward continuous casting method.

[0011] (2) rolling

[0012] Cold-rolling Cu-Al alloy rods with a diameter greater than Φ8mm improves the casting structure defects of the billet and obtains an ideal billet for drawing at the same time.

[0013] (3) Multi-pass drawing

[0014] The rolled Cu-Al alloy ...

Abstract

The invention provides an ultra-high tension copper wire and a preparation method thereof. The method comprises the steps of: ① preparing a Cu-Al master alloy rod with an Al content of 0.1-0.63 wt %; ② cold rolling the Cu-Al master alloy rod treatment; ③ drawing Cu-Al master alloy rod to obtain Cu-Al alloy wire with predetermined diameter; ④ internal oxidation treatment on Cu-Al alloy wire to obtain Cu-Al2O3 alloy wire with Al2O3 content of basically 0.2-1.2wt% ; and ⑤ drawing the resulting Cu-Al2O3 alloy wire to obtain an ultra-high tensile copper wire of the desired diameter. The ultra-high tension copper wire thus prepared has good electrical conductivity, high tensile strength and softening temperature, and is suitable for cutting-edge digital communication equipment, high-fidelity wires and voice coil wires, ultra-high magnetic field water-cooled copper wires or connectors. The invention prepares Al2O3 dispersion-strengthened copper alloy high-tensile wires by the overall internal oxidation method of Cu-Al alloy wires, which opens up a new way for the production of high-conductivity high-tensile copper alloy wires in my country.

Description

technical field [0001] The invention relates to a copper alloy wire material and its preparation method, more specifically, the invention relates to cutting-edge digital communication equipment, high-fidelity wires and voice coil wires, water-cooled copper wires for ultra-high magnetic fields and ultra-high tension copper wires for connectors and its preparation method. Background technique [0002] Ultra-high tension copper wires are widely used in cutting-edge digital communication equipment, high-fidelity wires and voice coil wires, water-cooled copper wires for ultra-high magnetic fields, and copper alloy wires for connectors. At present, the oxygen-free copper alloy rod used to produce the copper alloy wire in my country mainly relies on imports (mainly Japan). [0003] The aluminum oxide dispersion strengthened copper alloy prepared by the internal oxidation method introduces fine and dispersed alumina particles into the copper matrix, so that the alloy not only has h...
