- 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
- Popular brazing filler metal for HVAC and refrigeration connections
- Recommended joint clearance of 0.003 in to 0.006 in
- For brazing brass or copper-to-brass Stay-Silv® white flux is suitable for most applications
- 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
