Abstract
A method of manufacturing an aluminum alloy wire includes: forming a rough drawing wire composed of an aluminum alloy containing aluminum, an additive element, and unavoidable impurities, the additive element including Si and Mg; obtaining an aluminum alloy wire by performing a treatment on the rough drawing wire, wherein the treatment includes at least one or more wire drawing treatments; forming a first solution treatment material by forming a solid solution of the aluminum and the additive element and then performing a quenching treatment on the solid solution, wherein the first solution treatment is performed directly before the last of the one or more wire drawing treatments is performed; a second solution treatment that forms a second solution treatment material by forming a solid solution of the aluminum and the additive element and then performing a quenching treatment on the solid solution.
