Abstract
The invention discloses a copper-clad aluminum magnesium alloy wire and a production method thereof. The copper-clad aluminum magnesium alloy wire comprises a rare-earth aluminum magnesium alloy core wire and a copper layer cladding the core wire. The copper layer is bonded with the rare-earth aluminum magnesium alloy core wire through metallurgy. The copper-clad rare-earth aluminum magnesium alloy wire comprises 0.5-1% of magnesium, 0.45-0.65% of silicon and 0.2-0.5% of RE (rare earth), with the balance being aluminum and inevitable impurities. The RE refers to mixed rare earth elements, and one or more of cerium, lanthanum and yttrium are usually adopted. To solve the problem, the technical scheme includes that the production method includes A, smelting and refining the ingredients at the high temperature, and insulating and filtering alloy liquid after refining; B, pouring the alloy liquid obtained in the step A into an aluminum alloy ingot; C, rolling the aluminum alloy ingot obtained in the step B into an aluminum alloy rod; D, cladding the rolled aluminum alloy rod obtained in the step C with the copper layer; E, drawing the aluminum alloy rod obtained in the step D into the aluminum alloy wire.
