Rare earth copper alloy wire rod and preparation method thereof

Abstract

The invention relates to a rare earth copper alloy wire and a preparation method thereof. The rare earth copper alloy wire is characterized by comprising the following components in percentage by weight: 0.01 to 0.012 percent of zirconium, 0.25 to 0.29 percent of magnesium, 0.055 to 0.065 percent of silicon, 0.012 to 0.015 percent of lanthanum, 0.01 to 0.012 percent of cerium, 0.026 to 0.029 percent of antimony, 0.12 to 0.14 percent of chromium and the balance of copper. Compared with a conventional copper alloy wire, the copper alloy wire disclosed by the invention simultaneously has high strength and high electric conductivity; the tensile strength of the rare earth copper alloy wire reaches over 610Mpa; the electric conductivity of the rare earth copper alloy wire can reach over 72.0 percent IACS; the rare earth copper alloy wire is a high-strength high-electric-conductivity heat-resisting copper alloy wire of which the heat resistance reaches over 180 DEG C after long-term operation; power transmission capacity of the wire can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of alloy wire manufacture, and in particular relates to a rare-earth copper alloy wire used on a power transmission line and a manufacturing process thereof. Background technique [0002] In the past, the main component of wires used as transmission lines in my country was copper. Common steel-cored copper conductors, copper-clad steel-cored conductors, heat-resistant copper conductors, high-strength copper conductors, etc. used on transmission lines. However, the existing copper alloy wire has a series of problems such as low conductivity, low strength, no heat resistance, large difference in conductivity in different environments, and high wire consumption. Contents of the invention [0003] The object of the present invention is to provide a rare earth copper alloy wire and a preparation method thereof, and the produced copper alloy wire can meet the requirements of high elongation and high electrical ...
