Stay Silv 15 is a frequent choice for copper brazing. It has a wide melting range that allows operators to fill loose connections and "cap", or build up, around the finished joint. When heated above its liquidus, however, it will penetrate tight connections.
Stay Silv 15 is also a suitable choice to braze brass. In these applications operators should take care to avoid over heating the brass, and use Stay Silv white brazing flux.
Stay Silv 15 has historically been a popular brazing filler metal for HVAC and refrigeration connections. Its low phosphorus content provides brazed assemblies with good strength and ductility. Users should also consider Harris DynaflowÃ† as a lower cost option.
Stay Silv 15 is not recommended for brazing steel or other ferrous base metals. The phosphorus content promotes formation of a low ductility intermetallic with the ferrous base metal. It is sometimes used to braze selected low nickel content copper-nickel base metals, (90/10), but service suitability should be first established.
