Abstract (en)

[origin: EP2333127A1] A copper alloy material for electrical/electronic components, which is characterized by containing 0.7-2.5% by mass of Co, while containing Si in such an amount that the mass ratio between Co and Si (Co/Si) is not less than 3.5 but not more than 4.0, with the balance made up of Cu and unavoidable impurities. The copper alloy material is also characterized by having a crystal grain size of 3-15 [mu]m.
