Manufacture of powders of nickel-base brazing alloys
- 23 Downloads
A process has been developed for the manufacture of a Ni-Cr-Si-Fe-B brazing alloy in powder form, designated as PKh12N75S8R, and also brazing alloy powder No. 6MA, which is a mechanical mixture of 85% of PKh12N75S8R powder and 15% of molybdenum. Using alloy powder No. 6MA (instead of PKh12N75S8R) for brazing high-alloy steels raises the secondary melting (unbrazing) temperature of the brazed joint.
