Abstract

See full text

An aluminum alloy wire rod includes Mg: 0.1-1.0 mass %, Si: 0.1-1.2 mass %, Fe: 0.10-1.40 mass %, Ti: 0-0.100 mass %, B: 0-0.030 mass %, Cu: 0-1.00 mass %, Ag: 0-0.50 mass %, Au: 0-0.50 mass %, Mn: 0-1.00 mass %, Cr: 0-1.00 mass %, Zr: 0-0.50 mass %, Hf: 0-0.50 mass %, V: 0-0.50 mass %, Sc: 0-0.50 mass %, Co: 0-0.50 mass %, Ni: 0-0.50 mass %, and the balance: Al and inevitable impurities. In a cross section parallel to a wire rod lengthwise direction and including a center line of the wire rod, no void having an area greater than 20 μm2 is present, or even in a case where at least one void having an area greater than 20 μm2 is present, a presence ratio of the at least one void per 1000 μm2 is on average in a range of less than or equal to one void/1000 μm2.
