ABSTRACT:
The invention provides a material for sliding contacts that is suitable for a small-sized DC motor used in recent downsized CD players and is excellent in durability. A material for sliding contacts used in a commutator of a small-sized DC motor that consists essentially of 0.01 to 3.0% Ni by weight, 0.01 to 6.0% ZnO by weight and/or 0.01 to 3.0% MgO by weight, furthermore, in some cases, 0.01 to 5.0% Cu by weight, and the balance Ag, in which Ni metal particles, ZnO particles or MgO particles are dispersed in the matrix of Ag.
