Abstract
The invention relates to an aluminum alloy for wires and a preparation method thereof. The aluminum alloy for wires is composed of the following components in percentage by weight: 1.0-1.1% of copper, 0.03-0.05% of iron, 0.003-0.005% of silver, 0.003-0.005% of neodymium, 0.001-0.003% of tellurium, 0.001-0.003% of indium, 0.001-0.0015% of carbon, 0.003-0.005% of titanium, 0.003-0.005% of vanadium, 0.1-0.3% of nickel, 0.01-0.03% of tungsten, and the balance of aluminum and inevitable impurities. By using the technical scheme, the strength of the aluminum alloy wire is enhanced, the influence on the conductivity of the wire is small, and the toughness of the aluminum alloy wire is enhanced.
Description
technical field [0001] The invention belongs to the field of aluminum alloys, in particular to an aluminum alloy used as an electric wire 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, and toughness of pure alumi...
