Patent ID: 7651023

Claim:
A method for joining two metal components formed of nickel-based alloys, comprising the following steps: a) placing a joint-forming amount of a braze composition between the metal components which have been positioned in a close-fitting arrangement, wherein the braze composition comprises: about 10 to about 20 atom % palladium; and about 0.1 atom % to about 5 atom % (total) of at least one element selected from the group consisting of boron and silicon; about 2 atom % to about 16 atom % aluminum; about 7 atom % to about 15 atom % chromium; with the balance comprising nickel; b) heating the braze composition to a brazing temperature sufficient to melt the composition but not the metal components; and c) cooling the braze composition so that it re-solidifies and forms a joint between the components.
