Efficient and energy-saving copper-clad aluminum magnesium alloy wire and producing method thereof

Abstract

The invention discloses an efficient and energy-saving copper-clad aluminum magnesium alloy wire and a producing method thereof. The energy-saving copper-clad aluminum magnesium alloy wire is composed of a rare-earth aluminum magnesium alloy core wire and a copper layer coated on the core wire; the copper layer and the rare-earth aluminum magnesium alloy core wire are in metallurgical bonding; the copper-clad rare-earth aluminum magnesium alloy wire is composed of the components in proportion as follows: 0.5-1% of magnesium, 0.45-0.65% of silicon, 0.2%-0.5% of RE, and aluminum and unavoidable impurities of the balance. The RE is a mixed rare-earth element, and generally one or mixture of cerium, lanthanum and yttrium. The diameter of the copper-clad rare-earth aluminum magnesium alloy wire is 2-5 mm; the volume of the copper layer is 10-20% of that of the copper-clad rare-earth aluminum magnesium alloy wire; the weight of the copper layer is 25-35% of that of the copper-clad rare-earth aluminum magnesium alloy wire. The method of the invention comprises the specific steps of: smelting alloy liquid, casting and crystallizing, rolling, cladding and welding, and wire-drawing.

Problems solved by technology

[0004] As we all know, pure copper (wire) materials not only have high density and high production costs, but also have limited copper resources and cannot be regenerated; copper-clad aluminum (magnesium) alloy (wire) materials not only have poor electrical properties, but also have relatively high resistance and low electrical conductivity. , and the mechanical properties are relatively poor, the tensile strength is relatively low, the elongation is relatively small, it is easy to break, and the economic performance is relatively lacking, so the application range is relatively narrow, and a "renewal product" is needed to overcome the above-mentioned materials. defect
