DETAILS Stay-Silv 15 has proven its value for many years as it has been considered the industry's standard 15% silver alloy. This filler metal is excellent for situations in where close fit-up does not exist and where thermal expansion and service vibration are involved. Features A frequent choice for brazing copper, as copper is self-fluxing Wide melting range allows operators to fill loose connections and "cap", or build up around finished joint. When heated above its liquidus it will penetrate tight connections. Excellent for situations where close fit-up does not exist, and where thermal expansion and service vibration are involved. Popular brazing filler metal for HVAC and refrigeration connections. Can be used to braze brass with the use of appropriate brazing flux Suitable for brazing low nickel, (10% maximum), copper/nickel base metals Can be used for brazing copper-to-copper and copper-to-brass (using Stay-Silv" white brazing flux) applications. Corrosion resistance is generally similar to copper base metal, but phosphorus containing alloys 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 Conforms to the EU Reach & RoHS directive
