GF-02 is a Phos-copper brazing alloy that is primarily used for the joining of copper to copper on brazing joints where there is a slight gap. Recommended tolerances of .002 to .005” should be maintained. The small addition of silver allows the alloy fill gaps on the low end of the brazing temperature range. Fluidity will rapidly increase when approaching the end of the brazing temperature range. 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. Typical applications are air conditioning and refrigeration components including valves 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-02 is 1350 to 1500°F (732 to 816°C)
