Phos-copper-silver filler metal for brazing copper or brass used in the HVAC and refrigeration industries.


Dynaflow® melts and flows at temperatures very close to Stay-Silv® 15 and provides comparable brazed mechanical properties. This makes Dynaflow® an excellent cost-effective alternative to the 15% silver alloys. This premium, medium range silver alloy has been meticulously formulated to even tighter specifications than our standard copper-to-copper alloys.


  • Premium, medium-range, alloy for brazing copper or brass.
  • Excellent strength and ductility.
  • Economical replacement of 15% silver alloys.
  • When heated above its liquidus, can penetrate tight connections.
  • Wide melting range provides ability to fill loose connections and "cap" or "build-up" around the finished joint.
  • Self-fluxing on copper and copper-to-copper connections. Use Stay-Silv® white flux for brazing brass or copper-to brass.
  • Corrosion resistance is generally similar to the copper base metal
  • Not recommended for brazing steel or other ferrous base metals
  • Due to its phosphorus content, should not be used if the braze is exposed to sulfur or sulfur compounds in service.
  • Complies with the EU Reach & RoHS directive

Typical Applications

  • Copper-to-copper brazing
