Harris Products Group, 5H536R, Brazing Alloy, Phos-Copper, 1320-1500 F, Self-Fluxing, 0.003-0.006 in Joint Clearance

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

• Wide melting range allows the operator to fill loose connections
• Medium-range alloy for brazing copper-to-copper and copper-to-brass
• Well suited where close fit-up cannot be maintained
• A frequent choice for brazing copper as it is "self-fluxing"
• Fluidity rating 4
• Complies with the EU Reach & RoHS directive
• 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
• 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
