Abstract

PURPOSE:To surely form a stable one-side oxidized layer in the manufacture of an electrical contact material made of an internally oxidized Ag alloy stuck a base metal to one side by forming a layer in which an Ag concn. gradient is gradually reduced toward the oxygen-isolating side. CONSTITUTION:In the manufacture of the internally oxidized AG alloy 2 for electrical contact material stuck base metal 3 of Cu or its alloy to the brazing side, layer 1 in which an Ag concn. gradient is gradually reduced toward the metal 3 is formed on the oxygen-isolating side of the metal 3, and a contact material (Ag-Me) is placed on layer 1. This layered material is internally oxidized from internal oxidation side B by heating in an oxidizing atmosphere to form an internally oxidized layer of Ag-MeO. The resulting one-side internally oxidized Ag alloy 2 for electrical contact material has the internally oxidized layer on one side and base metal 3 for welding on the other side. Thus, this material can be manufactured stably.
