Description

[0001] technical field [0002] The invention belongs to the technical field of wires and cables, and in particular relates to a rare earth aluminum alloy wire. [0003] Background technique [0004] The price of copper has skyrocketed, and the cost of using copper wires is too high, which has caused great economic pressure on both manufacturers and users. However, due to the defects of aluminum in mechanical properties, poor connection performance and corrosion resistance, 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 wires, especially in the field of power cables. Although there are many patents on aluminum alloy wires, the comprehensive performance is not very good, and the comprehensive problems of electrical performance, corrosion resistance, wear resistance and h...
