Stay-Silv® White Brazing Flux 1/4 lb. jar


Stay-Silv® white brazing flux 1/4 lb. jar


Stay-Silv® white brazing flux is an all-purpose, low-temperature flux for use in silver brazing. It is formulated to provide smooth flux application, even coverage and excellent protection during braze heating cycles. It can be used with most ferrous and non-ferrous metals other than aluminum, magnesium or titanium. Ideal for silver brazing cast iron, copper, brass, bronze and steel. The flux turns clear (transparent) close the brazing application temperature, an indicator that it is ready to apply braze wire or rod. Post braze flux residue should be removed to avoid potential corrosion. Complies with the EU Reach & RoHS directive.


  • Homogeneous brazing flux ideally suited for use with a variety of base metals
  • Formulated to provide smooth flux application, even coverage and excellent protection during braze heating cycles
  • Recommended for brazing copper and copper alloys, except aluminum bronze
  • Used for brazing steel, stainless steel, nickel alloys and other ferrous base metals
  • Used with many high silver brazing filler metals
  • For use with many phosphorus-copper-silver alloys and brazing copper-to-brass
  • Used on applications requiring normal heat
  • Used with silver brazing alloys on all metals except aluminum, magnesium, or titanium
  • Activity range of 1050◦F - 1600◦F (565◦C - 870◦C)
  • Conforms to ANSI/AWS A5.31 Class FB3 A; AMS 3410; Federal Spec O-F-499, Type B; EN 1045 Type FH10
