AG-45% is a general-purpose cadmium-free brazing alloy for brazing with steel, copper, and brass. This silver alloy has the addition of tin to enhance flow and works well for wide clearances. It has a brazing temperature range of 1251 to 1495°F (677 to 813°C). It is also referred to “45T”. AG-45% is an excellent silver to work with Type U Paste Flux (copper, brass, and mild steels), Type G Paste Flux (mild steels and stainless steel) and Type H Black Paste Flux (copper, brass, mild steels, and stainless steel). All paste fluxes work with dissimilar base metals.

AG-00 is a Phos-copper brazing alloy that is primarily used for the joining of copper to copper on brazing joints with a tight and controlled fit-Up. Recommended tolerances of .001 to .003” should be maintained. The high percentage of phosphorus renders it a very fluid alloy. 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-00 is 1350 to 1500°F (732 to 843°C).
