Stay-Silv® 15 Phos-Copper Brazing Alloy

Stay-Silv® 15 phos-copper filler metal is the industry standard for air conditioning/refrigeration applications. Its melting range is useful in filling wider clearances while providing good service ductility. Complies with the EU Reach & RoHS directive.

• Stay-Silv® 15 phos-copper brazing alloy POP 0.050 x 1/8 x 20 in. 1 ea. mini-pak 7-stick tube
• Stay-Silv® 15 phos-copper filler metal is the industry standard for air conditioning/refrigeration applications. Its melting range is useful in filling wider clearances while providing good service ductility. Complies with the EU Reach & RoHS directive.
• Popular choice for copper brazing air conditioning and refrigeration connections
• Flows into tight connections when heated above its liquidus temperature
• 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.
• Popular brazing filler metal for HVAC and refrigeration connections
• Recommended joint clearance of 0.003 in. - 0.006 in. (0.08 mm - 0.15 mm)
• Flux not required for copper brazing as it is self-fluxing. For brazing brass or copper-to-brass Stay-Silv® white flux is suitable for most applications. Harris Eco Smart® boric acid free flux, powder or paste, is an excellent choice to promote sound brazed assemblies
• Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including Stay-Silv® 15, should not be used if the braze is exposed to sulfur or sulfur compounds in service
• Not recommended for brazing steel or other ferrous metals due to sufficient lack of joint ductility
• Suitable for brazing low nickel (10% maximum) copper/nickel base metals
• Complies with the EU Reach & RoHS directive
