Abstract

Disclosed is a copper alloy material containing 2.8-5.0 mass% of Ni and 0.4-1.7 mass% of Si, while suppressing S content to less than 0.005 mass%. The balance of the copper alloy material is composed of Cu and unavoidable impurities. This copper alloy material has a proof stress of not less than 800 MPa, and is excellent in bending workability and stress relaxation resistance.
