Abstract

An aluminum alloy wire rod having a composition comprising Mg: 0.10-1.00 mass %, Si: 0.10-1.00 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: 0.01-0.50 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 %, and Ni: 0.00-0.50 mass %. Mg/Si ratio is greater than 1. A dispersion density of compound particles having a particle size of 20 nm to 1000 nm is greater than or equal to 1 particle/μm². In a distribution of the compound particles in the aluminum alloy wire rod, a maximum dispersion density of the compound particles is less than or equal to five times a minimum dispersion density of the compound particles.
