Abstract
An aluminum (Al) alloy wire, which is an extra fine wire having a wire diameter of 0.5 mm or less, contains, in mass %, Mg at 0.03% to 1.5%, Si at 0.02% to 2.0%, at least one element selected from Cu, Fe, Cr, Mn and Zr at a total of 0.1% to 1.0% and the balance being Al and impurities, and has an electrical conductivity of 40% IACS or more, a tensile strength of 150 MPa or more, and an elongation of 5% or more. By producing the extra fine wire from an Al alloy of a specific composition containing Zr, Mn and other specific elements, though the extra fine wire is extra fine, it has a fine structure with a maximum grain size of 50 μm or less and is superior in elongation.
