Item Details

  • Stay-Silv® 5 is useful primarily where fit-up cannot be tightly controlled. Stay-Silv® 5 is a medium melting range alloy.


  • Medium-range silver brazing alloy designed for brazing copper-to-copper - copper is self-fluxing.
  • Can braze copper to low-zinc brass using Stay-Silv® white brazing flux.
  • Economical alternative to higher silver content alloys for copper and brass applications.
  • Somewhat more ductile than Harris® 0 or Stay-Silv® 2.
  • Well suited where close fit-up cannot be maintained.
  • Its wide melting range allows penetration into tight clearances and provides ability to fill wider gaps.
  • Solidus: 1190°F (643°C)
  • Liquidus: 1494 -1506°F (812-819°C)
  • Fluidity Rating: 3
  • Electrical Conductivity: 9.6% IACS
  • Electrical Resistivity: 18.1 Microhm/cm
  • Specific Gravity: 8.14
  • Brazing Temp Range: 1320-1500°F (716-816°C)
  • Recommended Joint Clearance: 0.003-0.006"
  • Not recommended for brazing steel or other ferrous base metals.
  • Stay-Silv® 5 should not be used if braze is exposed to sulfur or sulfur compounds in service.
  • Made in USA
