Abstract

See full text

An aluminum alloy wire rod has a composition including Mg: 0.10-1.0 mass %, Si: 0.10-1.20 mass %, Fe: 0.01-1.40 mass %, Ti: 0.000-0.100 mass %, B: 0.000-0.030 mass %, Cu: 0.00-1.00 mass %, Ag: 0.00-0.50 mass %, Au: 0.00-0.50 mass %, Mn: 0.00-1.00 mass %, Cr: 0.00-1.00 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: 0.00-0.50 mass %, Ni: 0.00-0.50 mass %, and the balance: Al and incidental impurities, Mg/Si mass ratio being 0.4 to 0.8. The aluminum alloy wire rod has a tensile strength of greater than or equal to 200 MPa, an elongation of greater than or equal to 13%, a conductivity of 47% IACS, and a ratio (YS/TS) of 0.2% yield strength (YS) to the tensile strength (TS) of less than or equal to 0.7.
