Stay-Silv® 5 is used primarily where fit-up cannot be tightly controlled. Stay-Silv® 5 is a medium melting range alloy.
Harris® Brazing Filler Metal, Series: Stay-Silv® 5, 1/2 x 1/8 in Dia, 28 in Length, #28, Stick, Chemical Composition: 5.9% Phosphorus, 5% Silver, Copper Balance and 0.15% Other, 1350 to 1550 deg F Brazing, Applicable Materials: Copper/Brass, Copper to Copper
- 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
