Problems solved by technology

[0002] my country is a big producer and exporter of electronic communication materials. For a long time, the terminal products produced by the electronic cable industry use almost pure copper wires. For this reason, a large amount of copper resources are consumed. However, my country's copper resources are in short supply, and the price of copper materials Also more expensive, resulting in increased production costs and end-consumption costs

Abstract

The invention discloses an aluminum magnesium alloy containing the rare earth element lanthanum. The rare earth element La is added into the aluminum magnesium alloy, and therefore the heat crack trend of the alloy is obviously reduced, the synthesized mechanical property of the alloy is improved, the strength of extension and the elongation of the alloy are obviously improved, inorganic elementslike Si in the system are removed, a small amount of metal Ce is added, and therefore the strength of extension and the elongation of the alloy are further improved. Aluminum magnesium alloy wires with the diameter being 3.0 mm are machined, the strength of extension can reach 380 MPa, and the elongation can reach 22%. Meanwhile, consideration is given to application cost, the added rare earth element La is less, the cost is economical, and the alloy has the wire prospect in actual industrial production.

Description

technical field [0001] The invention relates to the field of metal alloy material preparation, and relates to an aluminum-magnesium alloy containing rare earth element lanthanum and a preparation method thereof. Background technique [0002] my country is a big producer and exporter of electronic communication materials. For a long time, the terminal products produced by the electronic cable industry use almost pure copper wires. For this reason, a large amount of copper resources are consumed. However, my country's copper resources are in short supply, and the price of copper materials It is also more expensive, resulting in increased production costs and end-use costs. As a new type of shielding functional material that can replace pure copper round wire, aluminum-magnesium alloy wire is a new type of communication material. It is used for the outer conductor braided wire of signal transmission lines such as coaxial cables, and can be widely used in the field of information...
