  • AG-05 is a phos-copper that is used primarily for the joining of copper to copper and copper to brass where tight gaps cannot be maintained.
  • Typical applications are air conditioning and refrigeration components including valves, condensers and coils, water lines and heat exchangers.
  • This alloy is self-fluxing on copper joints. It is recommended that a flux such as our Type U Paste Flux be used when brazing copper to brass.
  • The brazing temperature range for AG-05 is 1325 to 1500°F (718 to 816°C)
  • Recommended for tolerances of .002 to .005”. This universal alloy has a lower phosphorus content which allows for loose fitting joints to be filled provided it does not exceed the upper range of the tolerance. Works with non-ferrous base metals such as copper and brass. It is not recommended for ferrous base metals such as steel and stainless steel.
