• Popular choice for copper brazing of air conditioning and refrigeration connections
• Flows into tight connections when heated above its liquidus temperature
• Excellent for situations where close fit-up does not exist and where thermal expansion and service vibration are involved
• Wide melting range allows the operator to fill loose connections
• Recommended joint clearance of 0.003" - 0.006" (0.08mm - 0.15mm)
• Use STAY-SILV® white flux to braze brass or copper-to-brass
• 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
• Conforms to the EU Reach & RoHS directive

For many years the standard of the industry, the 15% silver alloy has proven its value. This filler metal is excellent for situations in which close fit-up does not exist and where thermal expansion and service vibration are involved.
