Harris® Dynaflow® phos-copper brazing alloy filler metal 3/32" round x 36" long rod packed in a 25 lb. box is a popular choice for HVAC and refrigeration connections. Its melting range and copper joint strength makes it an excellent, lower cost replacement for 15% silver alloys. It is a frequent choice for copper brazing. The phosphorus addition makes it "self-fluxing" on copper. The wide melting range allows operators to fill loose connections and "cap" or "build-up" around the finished joint. When heated above its liquidus, it will penetrate tight connections.. Dynaflow® can also braze brass using an applicable brazing flux. Conforms to the EU Reach and RoHS directive.
Features
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
Not recommended for brazing steel or other ferrous base metals
Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys should not be used if the braze is exposed to sulfur or sulfur compounds in service
Phosphorus content promotes formation of low ductility intermetallic with the base metal
Conforms to the EU Reach and RoHS directive
