PROBLEM TO BE SOLVED: To provide an aluminum electric wire which has high electric conductivity in addition to high strength and elongation and can be used also as a signal line for automobiles.SOLUTION: The method for producing the aluminum electric wire comprises, in this order: a casting step of casting a roughly-drawn wire while adding magnesium to an aluminum raw material having an aluminum content of ≥99.7 mass% and ≤99.85 mass% so that the magnesium content is ≥0.5 mass% and ≤4.5 mass% of the total; a drawing step of drawing the roughly-drawn wire to obtain a drawn wire; an annealing step of annealing the drawn wire at a temperature of ≥300°C and ≤400°C; and a cooling step of cooling the annealed drawn wire. |
