Provided is an aluminum alloy wire in which tensile strength, elongation, and electrical conductivity are ensured and the ratio of the 0.2% yield strength (YS) to the tensile strength (TS) is low. This aluminum alloy wire has a composition which contains 0.1-1.0 mass% Mg, 0.1-1.2 mass% Si, 0.01-1.40 mass% Fe, 0.000-0.100 mass% Ti, 0.000-0.030 mass% B, 0.00-1.00 mass% Cu, 0.00-0.50 mass% Ag, 0.00-0.50 mass% Au, 0.00-1.00 mass% Mn, 0.00-1.00 mass% Cr, 0.00-0.50 mass% Zr, 0.00-0.50 mass% Hf, 0.00-0.50 mass% V, 0.00-0.50 mass% Sc, 0.00-0.50 mass% Co, and 0.00-0.50 mass% Ni, with the remainder comprising Al and unavoidable impurities, and in which the Mg/Si mass ratio is 0.4-0.8. The aluminum alloy wire has a tensile strength of 200 MPa or greater, an elongation of 13% or higher, an electrical conductivity of 47% IACS, and a ratio of the 0.2% yield strength (YS) to the tensile strength (TS), YS/TS, of 0.7 or less. |
