Harris® Stay-Silv® 5 phos-copper brazing alloy filler metal .050" x 1/8" flat x 20" long rod 28-stick tube is a medium range filler metal that is well suited where close fit-up cannot be maintained. This filler metal is somewhat more ductile than Harris® 0 or Stay-Silv® 2. It is designed for copper-to-copper applications, but also can be used on copper to low zinc brass by applying Stay-Silv® white brazing flux. Stay-Silv® 5 flows rapidly when heated quickly to its liquidus. This allows penetration into tight clearance connections. With slower heating, the filler metal melting range provides the ability to fill wider gaps. Stay-Silv® 5 is often chosen as an economical alternative to higher silver content filler metals for copper and brass applications. Conforms to the EU Reach and RoHS directive.
Features
Medium-range brazing alloy for copper-to-copper applications
A frequent choice for brazing copper as it is self-fluxing
Well suited where close fit-up cannot be maintained
Wide melting range allows the operator to fill loose connections and fill wider gaps
When heated quickly to its liquidus, allows penetration into tight clearance connections
Use Stay-Silv® white flux to braze low-zinc brass
The phosphorus content promotes formation of a low ductility intermetallic with the base metal
Corrosion resistance is generally similar to the copper base metal, but due to its phosphorus content should not be used if the braze is exposed to sulfur or sulfur compounds in service
Not recommended for brazing steel or other ferrous base metals
Conforms to the EU Reach and RoHS directive
Specifications
AWS A5.8 BCuP-3
ASME SFA 5.8 BCuP-3
Applications
Medium-range alloy used to braze copper, copper and brass-to-copper and copper-to-low zinc brass.
It can bridge gaps where close fit-up cannot be maintained.
Caution
Before use, read and understand the manufacturer's instructions, Safety Data Sheets (SDS) and your employer's safety practices
Keep your head out of fumes
Use enough ventilation, exhaust at the flame, or heat source, to keep fumes and gases from your breathing zone and the general area
