Abstract

PURPOSE: To manufacture an electric contact material of excellent properties, by adding at least one of Si and Ge to Ag, adding an element such as Au or Pt as an accessory additive to the Ag and causing Fe, Co or another element to be contained as an Si and Ge finely dispersing agent in the Ag to provide an Ag alloy and causing internal oxidation in the Ag alloy.
CONSTITUTION: At least one of Si and Ge is added to Ag so that the quantity of the added element is 1W17% by atom of all solutes. 1W5% by atom of at least one of Fe, Co, Ni and Cu is added to the Ag to finely disperse the Si and Ge. 1W10% by atom of at least one of Au, Pt, Pd, Rh, Ru, Qs and Ir is added as an accessory additive element to the Ag. An Ag alloy is thus prepared. This alloy is treated for internal oxidation at a temperature between 250°C and the eutectic point. This results in providing an electric contact material for light-load communication, which excels in antisticking property, contact resistance characteristic, anticorrosion property and antidischarge-wear property.
