Description
Stay-Silv 5HP is a medium melting range silver brazing alloy designed for joining copper-to-copper and copper-to-brass. The alloy has a wider melting range suitable for joining loose connections. When heated above its liquidus, however, the alloy is fluid and suitable for connections with close fit-ups. Complies with the EU Reach & RoHS directive.
Features
- Medium-range alloy for brazing copper-to-copper and copper-to-brass
- Brazing range of 1320oF – 1500oF (716oC – 816oC)
- A frequent choice for brazing copper as it is “self-fluxing”
- Flux not required for copper-to-copper brazing. For brazing brass Stay-Silv white flux is suitable for most applications. Harris Eco Smart boric acid free flux, powder or paste, is an excellent choice to promote sound brazed assemblies
- Well suited where close fit-up cannot be maintained
- Wide melting range allows the operator to fill loose connections
- Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including Stay-Silv 5HP, should not be used if the braze is exposed to sulfur or sulfur compounds in service
- Fluidity rating 4
- Recommended joint clearance of 0.003 in. – 0.006 in. (0.08 mm – 0.15 mm)
- Complies with the EU Reach & RoHS directive
