A make-and-break contact material which is less worn out and is able to achieve an increased life compared to a conventional material of Ag&mdash;CdO-based alloy, in an AC general relay used for a resistive load of about 1 to 20A in a range of AC 100V to 250V. In the present invention, the make-and-break contact material of Ag&mdash;Ni-based alloy used for a switching part performing electrical switching through mechanical switching operation is the make-and-break contact material of Ag&mdash;Ni-based alloy with Ni metal particles dispersed therein which is obtained through mixing and stirring 3.1 to 20.0 wt % of Ni powder, a certain amount of Li CO powder corresponding to 0.01 to 0.50 wt % of metal Li as an additive, and a balance being Ag powder to make a mixture with the above described powders uniformly dispersed therein, and through compacting and sintering the above described mixture.

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&mdash;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&mdash;Ni-based alloy that is produced in such a method that 0.7 to 3.0 wt. % Ni powder, an additive of Li CO 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.
