A method for manufacturing a high conductive Al alloy wire without conducting an annealing process includes: providing an Al alloy rod comprising 0.01 parts by weight to 0.08 parts by weight of Fe, Fe:Si=2 to 3:1 of Si and the balance Al and inevitable impurities, based on 100 parts by weight of an entire A1350 alloy; conform-extruding the Al alloy rod by passing through a dies of a conform extruder having a polygonal shaped structure to form a polygonal shaped Al alloy wire; cooling the extruded Al alloy wire to room temperature; and winding the cooled Al alloy wire using a winder.
