Superior Flux & Mfg. Co.
No. 650 brazing flux is formulated for use with cadmium-free silver alloy and gold alloy filler metals for brazing on copper, nickel, precious metal alloys and selected ferrous metals. It is fluoride-free and does not yield hydrofluoric acid or boron-trifluoride gases during the brazing process. As a result, it provides greater safety for mucous membranes and respiratory systems.
