Abstract

PURPOSE: To provide an electrical contact material made of sintered alloy of Ag, Ni and NiCr and having short arc duration, superior fusion bonding resistance, superior consumption resistance, superior contact resistance stability, etc.
CONSTITUTION: Ag powder, Ni powder and NiCr powder are mixed in a predetermined ratio, calcined, and sintered to obtain the desired electrical contact material. The NiCr powder consists of, by wt., 65W95% Ni and 35W5% Cr, preferably 80% Ni and 20% Cr. The resulting sintered alloy has a composition consisting of, by wt., 2.5W35.0% NiCr, 5W15% Ni and the balance Ag. In addition, this alloy is very useful as an electrical contact material applicable to a nofuse circuit breaker, etc.
