Nickel Brazing Alloys

Aufhauser Nickel Brazing filler alloys are chosen for applications requiring higher service temperatures, greater joint strength, and superior corrosion resistance.

Appropriate for joining heat and corrosion-resistant alloys such as stainless steels, nickel- and cobalt-base alloys and superalloys, Nickel Brazing Alloys are also ideally suitable for vacuum systems and diffusion brazing processes due to low vapor pressure properties. Commonly used in various joining and fabrication applications for aerospace, engines and turbines, food and chemical processes, nuclear energy, heat exchangers and cryogenic tank storage industries.

Typically available in paste, powder, spray, tape forms.
