Stay-Silv 5HP phos-copper brazing alloy 1/16 x 36 in. x 1 ea. 25 lb. box.
The Harris Stay-Silv 5HP Phos-Copper Brazing Alloy - 1/16 in (1.6 mm) - 25 lb Box- 5H336R is a phosphor-copper brazing alloy (BCuP-2). Phos-copper alloys are self-fluxing on copper and copper alloys — no separate flux is required when brazing copper to copper. However, flux IS required when brazing copper to brass, bronze, or steel. These alloys are widely used in HVAC/R applications for copper tubing joints.
- Compatible families: Stay-Silv
- Available diameters: 1/16"
Brazing alloys are selected by the base-metal pairing and the joint clearance. Silver content and flux requirements drive both cost and strength of the finished joint.
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.
- 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
