Abstract

A Cu-Ag-based alloy wire, including an alloy composition containing 1.00-6.00 mass% of Ag, with a balance being Cu and inevitable impurities, having metal structure including a matrix phase of Cu alloy phase and a second phase precipitate containing an Ag phase, having ≥950 MPa tensile strength when containing 1.00 mass%≤Ag<1.50 mass%, ≥1050 MPa tensile strength when containing 1.50 mass%≤Ag<3.00 mass%, ≥1200 MPa tensile strength when containing 3.00 mass%≤Ag<5.00 mass%, and ≥1450 MPa tensile strength when containing 5.00 mass%≤Ag≤6.00 mass%, and when L is a linear distance from a surface to a center in a transection of the wire, c1 is an Ag average concentration in a annular region having L/100 length from the surface toward the center, and c2 is an Ag average concentration in a central region having 99L/100 length from the center toward the surface, (c1-c2) being 1.00-3.00 mass%.
