摘要：
The present invention is aimed at providing a sliding contact material that has an alloy composition containing no harmful substance like Cd, especially excellent contact resistance properties, electrical functions that are good and is not subject to secular change, and abrasion resistance practically bearing comparison with conventional sliding contact materials, and is aimed at lengthening the life of a motor by the use of a sliding contact material having excellent durability as a commutator for a small direct-current motor. The present invention is a sliding contact material of an Ag—Ni-based alloy that is used in sliding part electrically switching on and off by mechanical sliding action, and the material is a sliding contact material of Ni metal particle-dispersed-type Ag—Ni-based alloy that is produced in such a method that 0.7 to 3.0 wt. % Ni powder, an additive of Li2CO3 powder corresponding to 0.01 to 0.50 wt. % Li after being converted to metal and the balance of Ag powder are mixed and stirred to form a uniformly dispersed mixture, then the mixture is treated with forming and sintering processes.
