Abstract

PURPOSE: To enhance the melt sticking resistance of a product contact material by well mixing Ag powder with Ni powder in a prescribed ratio, pressing and sintering the mixture once or more, and extrudion-molding the sintered body when an Ag-Ni composite electrical contact material is manufactured.
CONSTITUTION: Ag powder and Ni powder are weighed so heat 90wt% Ag powder and 10wt% Ni powder are contained. They are mixed with a V-type mixer for 2hr and continuously mixed with a ball mill for 2hr to disperse the Ni powder in the Ag powder uniformly and finely. This mixture is pressed and sintered once or more, and the sintered body is worked into a wire rod with an extruder. This wire rod is further drawn to a wire rod having 2.5mm diameter to manufacture an electrical contact material. This contact material contains Ni dispersed in Ag uniformly, and it has remarkably superior melt sticking resistance.
