Abstract

The invention provides an erbium-containing aluminum magnesium alloy wire and a production method thereof, and belongs to the technical field of alloy production. The erbium-containing aluminum magnesium alloy wire comprises the following components, in percentage by weight, of 1.3% to 2.5% of Mg, 0.4% to 0.8% of Er, 0.01% to 0.1% of Cr, 0.01% to 0.15% of Mn, 0.1% to 0.3% of Fe, 0.03% to 0.15% of Si and the balance Al, a total content of other impurities does not exceed 0.25%, and a content of a single impurity component does not exceed 0.1%. A manufacturing method of the erbium-containing aluminum magnesium alloy wire comprises the manufacturing steps of burdening, melting, refining, liquid discharging, horizontal traction casting, cast rod drawing, intermediate annealing, thick wire drawing, intermediate annealing, thin wire drawing and finished product annealing. The production efficiency is improved, the production cost is reduced, and the properties such as product strength and ductility can be improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum-magnesium alloy production, and in particular relates to an erbium-containing aluminum-magnesium alloy wire rod and a production method thereof. Background technique [0002] With the reform of rural broadcasting and television networks, the country's goal of building digital TV and networks for every village, my country's electronic communication industry has developed rapidly. For a long time, the terminal products produced by the electronic cable industry use almost pure copper wires, and the price of copper materials is also low. More expensive, resulting in increased production costs and end-consumption costs. As a new type of shielding functional material that can partially replace pure copper round wire, aluminum-magnesium alloy wire is typically used in the outer conductor braid of coaxial cables, and can also be used in the production of network cables, telephone cables, audio cables, USB...
