Abstract

A high-strength and high-conductivity heat-resistant aluminum alloy wire is characterized by comprising, by weight percentage, 0.075%-0.085% of copper, 0.032%-0.035% of scandium, 0.4%-0.5% of iron, 0.08%-0.12% of silicon, 0.02%-0.025% of zirconium, 0.8%-0.9% of manganese and the balance aluminum. Compared with an existing aluminum alloy wire, the strength and the electric conductivity of the high-strength and high-conductivity heat-resistant aluminum alloy wire are high at the same time; the tensile strength can be more than 265 Mpa; the electric conductivity can be more than 3.0% of IACS; the heat resistance can be more than 190 DEG C during long-time operation; and the power transmission capacity of the wire can be effectively improved.

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 aluminum wire for transmission lines and a manufacturing process thereof. Background technique [0002] In the past, the main component of wires used as transmission lines in my country was copper. However, due to the high price and cost of copper, and the advancement of technology, the application proportion of aluminum alloy wires is constantly increasing. Common steel-cored aluminum conductors, aluminum-clad steel-cored conductors, heat-resistant aluminum conductors, high-strength aluminum conductors, etc. used on transmission lines. However, the existing aluminum alloy wire has a series of problems such as low conductivity, low strength, heat resistance, large difference in conductivity in different environments, and high wire consumption. Contents of the invention [0003] The object of the ...
