About this item

  • Medium-range silver brazing alloy for copper-to-copper applications
  • More ductile than HARRIS® 0 or STAY-SILV® 2
  • A frequent choice for brazing copper as it is "self-fluxing"
  • When heated quickly to its liquidus, allows penetration into tight clearance connections
  • The melting range provides the ability to fill wider gaps
  • Use STAY-SILV® white flux to braze low-zinc brass
  • Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including STAY-SILV® 5, should not be used if the braze is exposed to sulfur or sulfur compounds in service
  • Not recommended for brazing steel or other ferrous base metals
  • The phosphorus content promotes formation of a low ductility intermetallic with the base metal
  • Conforms to the EU Reach & RoHS directive
