High performance aluminum-magnesium alloy wire and production process

Abstract

The invention relates to a high performance aluminum magnesium alloy wire and a production method, and the aluminum magnesium alloy wire comprises, in weight percent: 0.05 percent to 0.25 percent of manganese, 3.2 percent to 3.7 percent of magnesium, balance aluminum, and the weight percent of aluminum is controlled at 96 percent. When in production, the three materials are mixed and interfused highly by a natural gas melting furnace, and drop out impurities; then the fused mass is drawn into an aluminum magnesium alloy rod with diameter of 6.5mm, and the alloy rod is made into aluminum magnesium alloy wires with various specifications and diameters of between 0.1mm and 0.26mm through the stretching by a multifunctional wire drawing machine and then annealing and double wrapping. The alloy wire and the production method have advantages that: the chromium composition is replaced by increasing the manganese content, the alloy strength and corrosion resistance are improved by thinning crystallized grains, the environment will not be polluted, and the tensile property, extensibility and stitchability are good, high and strong.

Description

technical field [0001] The invention relates to the field of cables such as connecting wires and flat cables, and mainly relates to a high-performance aluminum-magnesium alloy wire and a production method thereof. Background technique [0002] my country is a big producer and exporter of electronic communication materials, but our country is not a developed country that develops high-quality products. For a long time, the terminal products produced by the electronic cable industry have used almost pure copper wires, which requires a large amount of copper resources. my country is a country that is very short of copper resources, and the price of copper materials has been affected by the shortage of resources. Soaring, resulting in a surge in production costs and end-consumption costs. The main diameter of shielded wires currently used at home and abroad is 0.1mm to 2.6mm.

Problems solved by technology

For a long period of time, the terminal products produced by the electronic cable industry have used almost pure copper wires, which requires a large amount of copper resources. my country is a country that is very short of copper resources, and the price of copper materials has been affected by the shortage of resources. Soaring, leading to a surge in production costs and end-consumption costs

The main diameter of shielded wires currently used at home and abroad is 0.1mm to 2.6mm. The shielding performance of the product is relatively simple, the overall performance cannot be improved proportionally, and the application range is also limited.
