Harris® Phoscopper Brazing Alloy, 1/8 in Diameter, 20 in Length, 1320 to 1500 deg F, Composition: 2% Brazing Filler Metal - Silver 4.8-5.2, Phosphorus 5.8-6, 0.15% Maximum Copper Balance, Others (Total)

• Medium-range silver brazing alloy for copper-to-copper applications
• More ductile than HARRIS® 0 or STAY-SILV® 2
• A frequent choice for brazing copper as it is "self-fluxing"
• When heated quickly to its liquidus, allows penetration into tight clearance connections
• The melting range provides the ability to fill wider gaps
• Use STAY-SILV® white flux to braze low-zinc brass
• Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including STAY-SILV® 5, should not be used if the braze is exposed to sulfur or sulfur compounds in service
• Not recommended for brazing steel or other ferrous base metals
• The phosphorus content promotes formation of a low ductility intermetallic with the base metal
• Conforms to the EU Reach & RoHS directive
