Abstract

The invention provides a high-strength high-conductivity heatproof copper alloy wire rod and a preparation method thereof. The wire rod comprises the following components: on the basis of weight percentage, 1 to 1.2 of silicon, 0.2 to 0.3 of magnesium, 0.02 to 0.04 of vanadium, 0.01 to 0.02 of titanium, 0.06 to 0.08 of manganese, 0.025 to 0.035 of lutecium and 0.05 to 0.07 of yttrium, with the balance being copper. According to the invention, the component silicon may lead to slight reduction of conductivity, improvement of strength and reduction of toughness, which causes easier fracture of the wire rod in the process of wire drawing; however, the components consisting of magnesium, vanadium and the like are added and a formula and proportions are optimized, so the copper alloy wire rod has high strength and high conductivity.

Description

technical field [0001] The invention belongs to the technical field of alloy wire manufacture, and in particular relates to a high-strength, high-conductivity and heat-resistant copper wire for transmission lines and a manufacturing process thereof.
