Abstract

PURPOSE: To enhance the contact performance and melt sticking resistance of the resulting electrical contact material by internally oxidizing an Ag alloy contg. Sn as a solute metal, In in an amount about equal to or smaller than the amount of the Sn and a small amount of an iron group element or alkaline earth metal.
CONSTITUTION: An Ag alloy contg. about 5W10wt% Sn as a solute metal to Ag, In in an amount about equal to or smaller than the amount of the Sn and a 0.01W 0.5wt% iron group element or alkaline earth metal is forged, rolled to a sheet, and internally oxidized by heating in an oxygen atmosphere. The resulting electrical contact material is free from Cd, etc. harmful to the human body, contains such a conventionally impossible large amount of Sn, and has a structure composed of uniform fine crystals. Accordingly, this material has high contact-performance and melt-sticking resistance.
