PROBLEM TO BE SOLVED: To prevent annealing crack in nickel silver. SOLUTION: In nickel silver containing, as fundamental components, 12 to 20% Ni, 17 to 27% Zn and <=0.5% Mn, and the balance substantial Cu, the content of H is controlled to 0.0001% or less, and the content of sulfur is controlled to 0.0020% or less to obtain a Cu-Ni-Zn alloy improved in annealing crack property.
