Rare earth high iron aluminum alloy conductor material

Abstract

The invention discloses a rare earth high-iron aluminum alloy conductor material, which comprises 0.4 to 1.5 weight percent of Fe, 0.3 to 1.3 weight percent of rare-earth element, 0.01 to 0.4 weight percent of one or several of Sc, Er, Ca, Sb and Mg and the balance of aluminum and inevitable impurities. The aluminum alloy material has various performance indexes of a high-elongation aluminum alloy material for a cable and has excellent heat resistance and corrosion resistance; therefore, the material has higher current carrying capacity.

Description

technical field

[0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a rare-earth high-iron aluminum alloy conductor material. Background technique

[0002] The price of copper has skyrocketed, and the cost of using copper cables is too high, which has caused great economic pressure on both manufacturers and users. However, due to defects such as poor mechanical properties, connection performance and corrosion resistance of aluminum, the purpose of replacing copper cables cannot be achieved. , The aluminum alloy material has been improved in composition and process, so that the aluminum alloy has improved the defects of pure aluminum, so it can achieve the purpose of replacing copper cables, especially in the field of power cables. For example, the authorized invention patent 200910116635.7 discloses a high-elongation aluminum alloy material for cables and its preparation method. This patent provides an aluminum alloy...
