Document Type and Number:
WIPO Patent Application WO/2011/125017
Kind Code:
A1
Abstract:
The invention relates to a method for brazing two or more parts. A hard solder having a composition consisting of NiRestCraBbPcSid having 20 atom % < a < 22 atom %; 1.2 atom % ≤ b ≤ 3.6 atom %; 12.5 atom % ≤ c ≤ 14.5 atom %; 0 atom % ≤ d ≤ 1.5 atom %; incidental impurities ≤ 0,5 atom %; the rest being Ni, is introduced between two or more parts to be joined in order to form a bond, wherein the parts to be joined have a higher melting temperature than the hard solder. The bond is heated to a temperature between 1020°C and 1070°C and is cooled, forming a brazed joint between the parts.
