A copper alloy material excellent in the resistance to corrosion caused by lubricating oils containing sulfur-base additives. The alloy comprises from over 5 to 50 % Ni, 0.1-2 % Ag and the balance consisting substantially of Cu, and optionally contains at least one member selected among (1) up to 20 % Sn, up to 0.5 % P, up to 5 % Al, up to 1 % Si, up to 5 % Mn, up to 30 % Zn, up to 10 % Fe and/or up to 1 % Sb, (2) up to 30 % in total of Pb and/or Bi, (3) up to 30 % in total of graphite MoS2, WS2 and/or BN, (4) up to 20 % in total of Al2O3, Sic, SiO2, Fe3P, AlN, Si3N4, Tic, WC, BN, NiB and/or Feb, and (5) 0.001-1 % S. |
