NICKEL BASED ALLOYS
These brazing alloys are generally used when specifications require good corrosion resistance and/or extreme service temperature (both high and subzero) properties.
Ideal for brazing of stainless steels and nickel based alloys.
They find numerous applications in the manufacturing of heat exchangers, diamond tools, and high-tech sectors such as aerospace industry.
Brazing is performed under a protective, reducing atmosphere, or in vacuum.
Available as powder and paste.
Some of these alloys are also available as amorphous brazing foils.
Some of these alloys are also available as rings.
