Harris® Brazing Rings are a convenient way to braze joints for copper pipe and tubing applications. The Brazing Rings are available in a variety of sizes to create tight and leak-proof joints. Made up of 15% silver, this product is a very popular brazing filler metal for HVAC and refrigeration connections. It has a wide melting range that allows operators to fill loose connections and “cap”, or build up, around the finished joint. When heated above its liquidus, however, it will penetrate tight connections. Its low phosphorus content provides brazed assemblies with good strength and ductility. 

Features:

• Solidus- 1190ºF (643°C)
  
• Liquidus- 1475°F (802°C)
  
• Density- 0.305 (lb/cu.in) 
• Excellent corrosion resistance
• Electrical conductivity- 9.9 (% IACS)
  
• Electrical resistivity- 17.4 (microhm/cm)

Chemical Composition:

• Silver- 14.5 - 15.5
• Phosphorus- 4.8 - 5.2
• Copper- remainder
• Other(total)- 0.15

*Brazing Rings are not recommended for brazing steel or other ferrous base metals. The phosphorus content promotes formation of a low ductility intermetallic with the ferrous base metal. It is sometimes used to braze selected low nickel content copper-nickel base metals, (90/10), but service suitability should be first established.
