Harris Products Group, 6H536S, Brazing Alloy, Medium Melting Range, Phos-Copper, Copper-to-Copper; Copper-to-Brass

Stay-Silv® 6HP 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 silver brazing alloy for copper-to-copper applications
• More ductile than Harris® 0 or Stay-Silv® 2
• Complies with the EU Reach & RoHS directive
• Use Stay-Silv® white flux to braze brass or copper-to-brass
• Not recommended for brazing steel or other ferrous base metals
• Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including Stay-Silv® 6HP, should not be used if the braze is exposed to sulfur or sulfur compounds in service
• The phosphorus content promotes formation of a low ductility intermetallic with the base metal
• Used in rod form for manual braze applications, but can be formed as brazing rings or on spools for semi-automated applications
