Abstract

An aluminum alloy wire rod has a composition consisting of 0.1-1.0 mass % Mg; 0.1-1.0 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; 0.00-0.50 mass % Ni; and the balance being Al and incidental impurities, wherein at least one or none of Ti, B, Cu, Ag, Au, Mn, Cr, Zr, —Hf, V, Sc, Co and Ni is contained in the composition. A dispersion density of an Mg 2 Si compound having a particle size of 0.5 μm to 5.0 μm is less than or equal to 3.0×10 −3 particles/μm 2 . In a sectional structure, a concentration of each of Si and Mg other than a compound is less than or equal to 2.00 mass %.
