Have Questions About This Product?

 

Stay-Silv® 6 is slightly more fluid and can be used where closer tolerances are available. It is somewhat more ductile than Harris®.
  • Stay-Silv® 6 is medium range silver brazing filler metal designed for copper-to-copper applications
  • Can also be used on copper-to- brass with appropriate brazing flux
  • Has lower phosphorus content than the AWS BCuP- 4 classification, (Stay-Silv® 6HP), this creates an alloy well suited for many brazing applications and the melting range makes it useful for assemblies with wider clearance
  • Often used in rod form for manual braze applications but is a good choice formed as brazing rings or on spools for semi-automated applications
  • Not recommended for brazing steel or other ferrous base metals, as the phosphorus content promotes formation of low ductility intermetallic with the base metal
  • Corrosion resistance is generally similar to copper base metal, but phosphorus containing alloys, including Stay-Silv® 6, should not be used if the braze is exposed to sulfur or sulfur compounds in service
  • Medium range alloy is well suited where close fit-up cannot be maintained
  • Filler metal is somewhat more ductile than phos copper or Stay-Silv® 2
