The invention discloses a production process for an aluminum-magnesium alloy wire. The production process for the aluminum-magnesium alloy wire comprises the following steps: (1) cold-rolling an aluminum-magnesium alloy rod, of which the diameter is 9.5 mm to 5.5 mm, to obtain a steel wire rod; (2) annealing the 5.5 mm steel wire rod at a temperature of 400-500 DEG C to obtain the annealed steel wire rod; and (3) drawing the annealed steel wire rod in a primary single mode to 4.4 mm and drawing the annealed steel wire rod in a secondary single mode to 3.2 mm, carrying out micro-scraping on thesurface, and finally, drawing the wire to 1.2 mm in a water tank to obtain the aluminum-magnesium alloy wire. The production process for the aluminum-magnesium alloy wire is suitable for processing high strength aluminum-magnesium alloy rod into the aluminum-magnesium alloy wire. By matching cold rolling with drawing, the process solves the problem that the aluminum-magnesium alloy wire is high in surface rate of defect and frequent to break in the production process, the breaking rate is reduced by 50%, and the production method is suitable for industrial batch production.
