Abstract

The invention discloses a silver-neodymium-boron containing aluminum alloy conductor and a preparation method thereof. The silver-neodymium-boron containing aluminum alloy conductor is prepared from, by mass, 0.05%-0.50% of Nd, 0.5%-1.5% of Ag, 0.005%-0.010% of B, 0.03%-0.05% of Mo, 0.02%-0.05% of Si, 0.1%-0.2% of Ru and the balance Al and inevitable impurities. The rare earth element Nd is added, the performance of other alloy elements is coordinated, so that on the premise that the alloy conductor has high electric conductivity, the mechanical performance and corrosion resistance of the alloy conductor are optimized to a large degree, and the requirement for long-span electric transmission lines can be met.

Description

technical field [0001] The invention belongs to the technical field of alloy wire preparation, and in particular relates to an aluminum alloy wire containing neodymium, silver and boron elements and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy, the construction of the electric power industry is showing a trend of rapid development. The large-span transmission lines under construction have been developed and extended to high-voltage, large-capacity, and long-distance. Only using traditional wires can no longer meet the needs. The strategic deployment of west-to-east power transmission, north-south mutual supply, and national networking and the demand for large-span transmission lines. [0003] In the power industry, the transmission of wires has a great impact on the power industry. The material and structure of the wire determine the resistance and conductivity of the wire. Larger resistance and lowe...
