Abstract

PURPOSE: To manufacture the titled material with stabilized contact resistance while maintaining the high electrical conductivities of Ag and Cu by mechanically mixing surface-oxidized Cu powder or wire rods with Ag powder or wire rods after which the mixture is compressed once or more, sintered in a nonreducing atmosphere, and plastically worked.
CONSTITUTION: Powder, wire rods or cut pieces of surface-oxidized Cu are mechanically mixed with powder, wire rods or cut pieces of Ag. The mixture is compressed once or more and sintered in a nonreducing atmosphere at a temp. below the eutectic point (780°C) of Ag-Cu. At this time, the sintering is carried out in a nonreducing atmosphere so as to protect the oxide film on the Cu surface. The sintered body is plastically worked to obtain a composite electrical contact material with enhanced melt sticking resistance as well as said characteristics. This material has a 3-phase composite structure of Ag-Cu-CuOX.
