<P>PROBLEM TO BE SOLVED: To provide an aluminum alloy having high toughness and high electric conductivity, an aluminum alloy wire, an aluminum alloy stranded wire, a covered electric wire, a wire harness, and a method for producing the aluminum alloy wire. <P>SOLUTION: The aluminum alloy wire contains not less than 0.005 to 2.2 mass% of Fe with the rest being Al and impurities. The aluminum alloy wire may further contain one or more kinds of additional element selected from among Mg, Si, Cu, Zn, Ni, Mn, Ag, Cr, and Zr in a total amount of 0.005 to 1.0 mass%. The Al alloy wire exhibits an electric conductivity of 58% IACS or above and an elongation of 10% or above. The Al alloy wire is produced via successive steps of casting, rolling, wire drawing, and softening treatment. Since the Al alloy wire is subjected to the softening treatment, the wire is excellent in toughness such as elongation and impact resistance, thus enabling reduction of fracture of the electric wire in the vicinity of a terminal portion when the wire harness is installed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
