ABSTRACT:
A nickel-palladium-based brazing alloy is disclosed having a composition consisting essentially of about 38 to about 55 atom percent palladium, about 19 to about 34.5 atom percent iron, about 11 to about 20 atom percent silicon, the balance being essentially nickel and incidential impurities. These alloys are especially suited for use as brazing filler metals in joining stainless steels and/or superalloys at temperatures above about 1000.degree. C. A process for brazing honeycomb structures formed at least in part from stainless steels and/or superalloys is also disclosed.
