Nickel Brazing Alloys
Brazing of nickel, chromium and iron-containing metals, stainless steel
Nickel Brazing alloys are applied for high temperature applications and where corrosion resistance is important. They are also used for extremely low temperature applications like contact with liquid gases.
Inert gas atmosphere is recommended. Due to their low vapour pressure, vacuum brazing is permitted.
