Description
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.
Features
- 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
