PURPOSE:To obtain a Cu series bearing allay improved in corrosion resistance while its seizing resistance and fatigue resistance are secured by adding specified amounts of Bi and Pb to Cu or furthermore adding at least one kind from among Sn, Zn, Si, Sb, P and Ni thereto. CONSTITUTION:Cu is incorporated with, by weight, >4 to 35% Bi and 0.2 to 1.5% Pb or furthermore incorporated with at least one kind from among 0.1 to 5% Sn, 0.1 to 1% Zn, 0.1 to 1% Si, 0.1 to 1% Sb, 0.01 to 1% P and 0.1 to 5% Ni, by which a Cu series bearing allay remarkably excellent in corrosion resistance while the seizing resistance and fatigue resistance of the conventional Cu-Pb series bearing allay are maintained can be obtd. |
