Metglas High Performance Brazing Filler Metals

Metglas® Brazing Foils (MBF's) and preforms provide extensive manufacturing and performance advantages over conventional metal joining materials. This unique form of amorphous nickel based brazing filler metal can substitute for previously used copper foil or nickel powder to braze stainless steel base metal. This amorphous nickel foil provides high strength and outstanding corrosion resistance of brazed joints.

Metglas Brazing Foils can be slit to specific widths and/or stamped into precise shapes for any application.
