Abstract (en)

A copper alloy material for an electric/electronic part, containing Co 0.5 to 2.5 mass% and Si 0.1 to 1.0 mass%, at a ratio of Co/Si of 3 to 5 in terms of mass ratio, with the balance of Cu and inevitable impurities, which is obtained by subjecting to a solution treatment at a temperature (°C) from 800°C to 960°C and lower than -122.77X 2 + 409.99X + 615.74, in which X represents the Co content in mass%.
