Abstract
An aluminum alloy, an aluminum alloy wire, an aluminum alloy stranded wire, a covered electric wire, and a wire harness that are of high toughness and high electrical conductivity, and a method of manufacturing an aluminum alloy wire are provided. The aluminum alloy wire contains not less than 0.005% and not more than 2.2% by mass of Fe, and a remainder including Al and an impurity. It may further contain not less than 0.005% and not more than 1.0% by mass in total of at least one additive element selected from Mg, Si, Cu, Zn, Ni, Mn, Ag, Cr, and Zr. The Al alloy wire has an electrical conductivity of not less than 58% IACS and an elongation of not less than 10%. The Al alloy wire is manufactured through the successive steps of casting, rolling, wiredrawing, and softening treatment. The softening treatment can be performed to provide an excellent toughness such as elongation and impact resistance and thereby reduce fracture of the electric wire in the vicinity of a terminal portion when the wire harness is installed.
