Abstract

The invention discloses a Gu-Nd-Au-B alloy lead and a preparation method thereof. The Gu-Nd-Au-B alloy lead comprises the following elements in percentage by mass: 0.05-0.50% of Nd, 0.5-1.5% of Au, 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 of Gu and inevitable impurities. The rare earth element Nd is added to coordinate the performances of other alloy elements, so that the alloy lead greatly optimizes the mechanical performance and the corrosion resistance under the precondition of higher electric conductivity, and can satisfy the demands of long-span power transmission lines.

Description

technical field [0001] The invention belongs to the technical field of alloy wire preparation, and in particular relates to a Gu-Nd-Au-B alloy wire 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 lower conductivity limit the application of wires i...
