Metglas® Brazing Foil

 

Advantages & Benefits of Metglas Brazing Foils

Metglas Brazing Foils (MBF's) provide extensive manufacturing and performance advantages over conventional brittle brazing filler metals
  • Advantages of brazing with MBF's
    • 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. Adhesive bonding and soldering
      • MBF's offers superior strength, flexibility and temperature and oxidation resistance.
    • 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. 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.

       

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