Another current applying equipment for solution treatment may be installed in tandem at upstream side of the annealing while running equipment. In place of the annealing while running equipment, a current applying equipment may be connected in tandem for age-treatment. By using those equipments, age-precipitation copper alloy wire having the diameter of from 0.03 mm to 3 mm may be obtained.
