Metglas® Brazing Foil & Preforms

The advent of Metglas Brazing Foils (MBF's) from Metglas, Inc. enables cost-effective, reject-free production of stronger and more efficient corrosion resistant heat exchangers. This unique form of amorphous nickel-based brazing filler metal can substitute for previously used copper foil to braze stainless steel base metal. High strength and outstanding corrosion resistance of brazed joints are achieved when using Metglas Brazing foils.

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