Abstract

The invention relates to an aluminium alloy conductor and a preparation method thereof. The aluminium alloy conductor comprises the following components in percentage by weight: 1.0-1.1% of Cu, 0.03-0.05% of Fe, 0.001-0.0015% of C, 0.003-0.005% of Ti, 0.003-0.005% of V, 0.1-0.3% of Ni, 0.01-0.03% of W, 0.003-0.005% of La-containing rare earth and the balance of Al and inevitable impurities. By adopting the technical scheme provided by the invention, the strength of the aluminium alloy conductor is improved while the influence on the conductivity of the conductor is less, and the toughness of the aluminium alloy conductor is improved.

Description

technical field [0001] The invention belongs to the field of aluminum alloys, in particular to an aluminum alloy used as an aluminum alloy wire for electric wires and a preparation method thereof. Background technique [0002] In general, except for outdoor transmission wires, the wires in other equipment are mainly copper or copper alloy wires. This is mainly because the conductivity of copper or copper alloy wires is much higher than that of other metals in wires of the same diameter. . With the increase of electrical equipment, the amount of copper or copper alloy used as a wire is also increasing. On the one hand, copper is a precious metal, and on the other hand, it has a higher density, which increases the weight of the wire. The energy consumption is contradictory. Therefore, aluminum, which is also relatively high in conductivity and low in density, is used to make wires, and has received widespread attention. [0003] However, the strength, fatigue resistance, an...
