Abstract

PURPOSE: To improve consumption resistance, low contact resistance, electrical conductivity, and machinability, by adding specific amounts of rare earth elements of oxides of rare earth elements to an arc-resistant conductive material composed of W-base or WC-base alloy.
CONSTITUTION: In the arc-resistant conductive material composed of W- or WC-base alloy, 0.1W10wt%, of rare earth elements and/or oxides of rare earth elements are incorporated so as to improve various characteristics of the above material and to enable the prolongation of the service lives of electric contacts, electrodes for electric discharge machining, etc. It is preferable that one or more elements among Y, La, and Ce and one or more kinds among the oxides of the above elements are used as the above rare earth elements and the oxides of them, respectively. It is also preferable to use Ag-WC alloys containing 30W70% Ag as the above WC-base alloy and, as the W-base alloy, it is preferable to use Ag-W alloys containing 20W60% Ag and further Cu-W alloys containing 20W60% Cu can also be used. Moreover, it is preferable that wettability to Ag is improved by incorporating ≤2% of iron group elements and/or Cu to the above arc-resistant conductive material.
