Abstract:
1. An aluminum alloy wire material, which has an alloy composition consisting essentially of: 0.1 to 0.4 mass % of Fe, 0.1 to 0.3 mass % of Cu, 0.02 to 0.2 mass % of Mg, and 0.02 to 0.2 mass % of Si, and further consisting essentially of 0.001 to 0.01 mass % of Ti and V in total, with the balance being Al and unavoidable impurities, wherein a grain size is 5 to 25 μm in a vertical cross-section in a wire-drawing direction of the wire material, wherein, according to JIS Z 2241, a tensile strength (TS) is 80 MPa or more, an elongation (El) is 15% or more, and a 0.2% yield strength (YS; MPa) satisfies, together with the TS, a relationship represented by formula: 1.2≦(TS/YS)≦1.5, and wherein an electrical conductivity is 55% IACS or more.
