Stay-Silv® 5 silver brazing filler metal designed for copper-to-copper applications |
Also used on copper-to-low zinc by applying Stay-Silv® white brazing flux |
Stay-Silv® 5 will flow rapidly when heated quickly to its liquidus, this allows penetration into tight clearance connections, with slower heating the alloy melting range provides ability to fill wider gaps |
Economical alternative to higher silver content alloys for copper and brass applications |
Not recommended for brazing steel or other ferrous base metals, as the phosphorus content promotes formation of low ductility intermetallic with the base metal |
Corrosion resistance is generally similar to copper base metal, but phosphorus containing alloys, including Stay-Silv® 5, should not be used if the braze is exposed to sulfur or sulfur compounds in service |
Medium range alloy is well suited where close fit-up cannot be maintained |
Filler metal is somewhat more ductile than Harris® or Stay-Silv® 2 |
