Harris Products Group, 5H636S, Brazing Alloy, Phos-Copper, 1320-1500 F, Self-Fluxing

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

• Complies with the EU Reach & RoHS directive
• Fluidity rating 4
• Well suited where close fit-up cannot be maintained
• 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
• 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
• Brazing range of 1320oF - 1500oF (716oC - 816oC)
• Medium-range alloy for brazing copper-to-copper and copper-to-brass
• Wide melting range allows the operator to fill loose connections
• Recommended joint clearance of 0.003 in. - 0.006 in. (0.08 mm – 0.15 mm)

• Weight: 1.02 lbs
• Brazing Range: 1320 F - 1500 F (716 C - 816 C)
• Joint Clearance: 0.003 in - 0.006 in (0.08 mm 0.15 mm)
• Material: Phosphorus 6.6-6.7%, Copper remainder, Silver 4.8-5.2%, Other 0.15%
• Melting Range: Medium
• Fluidity Rating: 4
• Flux Requirement: No flux for copper-to-copper; Stay-Silv white flux for brass
• Corrosion Resistance: Similar to copper base metal; avoid sulfur exposure
• Compliance: EU REACH, RoHS
