STAY-SILV 15 Copper Brazing Alloy - 1/8 in - 20 in

STAY-SILV 15 phos-copper filler metal is the industry standard for air conditioning/refrigeration applications. Its melting range is useful in filling wider clearances while providing good service ductility. Conforms to the EU Reach & RoHS directive.


  • A frequent choice for brazing copper, as copper is self-fluxing
  • Wide melting range allows operators to fill loose connections and "cap", or build up around finished joint. When heated above its liquidus it will penetrate tight connections
  • Excellent for situations where close fit-up does not exist, and where thermal expansion and service vibration are involved
  • Popular brazing filler metal for HVAC and refrigeration connections
  • Can be used to braze brass with the use of appropriate brazing flux
  • Suitable for brazing low nickel, (10% maximum), copper/nickel base metals
  • Can be used for brazing copper-to-copper and copper-to-brass (using Stay-Silv" white brazing flux) applications
  • Corrosion resistance is generally similar to copper base metal, but phosphorus containing alloys should not be used if the braze is exposed to sulfur or sulfur compounds in service
  • Not recommended for brazing steel or other ferrous metals due to sufficient lack of joint ductility
  • Conforms to the EU Reach & RoHS directive
