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.

APPLICATIONS FOR BRAZING FOIL
ADVANTAGES AND BENEFITS OF MBFs
Metglas Brazing Foils (MBF’s) provide extensive manufacturing and performance advantages over conventional brittle brazing filler metals. Some of these advantages include a wide variety of widths and thickness for any type of project, corrosive resistance for long lasting stability and ease of installation.
Click to see Benefits
- Unique 100% metallic foil form possesing outstanding ductility
- MBF’s bend 180° without fracturing to comply with complex joint geometries to ease placement fixturing; ductile enough to be mechanically stamped and shaped to three-dimensional configurations.
- Wide range of brazing temperatures
- Covering melting temperatures from 950°C (1742°F) to 1195°C (2183°F).
- Contaminant-free
- For prolonged brazing furnace life.
- Fast melting and outstanding wetting and flow
- For void-free, optimum strength joints.
- Wide range of base metals successfully brazed
- Covering but not limited to all stainless steels, super alloys, hard cemented carbides and low carbon steels.
- Wide range of widths
- For easy brazing of small and large areas.
- Range of thicknesses available
- For optimized joint gaps, including very thin foil, 20µm (0.78 mil) for decreased erosion of base metal.
- Ease of assembling automation
- For enhanced manufacturing efficiency.
- Consistent performance
- A virtually reject-free brazing operation in one heating cycle.
- Precise metering and ability to be used as preforms
- Eliminates waste and creates high quality joints.
- Unlimited shelf life
Click to see Advantages
- VS. Mechanically-fastened joints
- MBF’s provides higher strength, leak tightness, and superior resistance to shock and vibration. Lighter gauge base metals may be used for substantial weight savings since MBF’s provide continuous, uniform joints.
- VS. Welding
- MBF’s provides much higher processing efficiency. The lower melting temperature of MBF’s eliminates melting of base metals. No joint cleaning or finishing is required.
- VS. Adhesive bonding and soldering
- MBF’s offers superior strength, flexibility and temperature and oxidation resistance.
- VS. Powder, paste and tape forms of brazing
- MBF’s contains no organic binders, thus eliminating contaminating residues and reducing furnace cycle times. Completely homogeneous, 100% metal MBF’s alloy optimizes brazed joint formation and performance. Reliable melting and flow reduces rework and rejects too.
