Gaseous fluxes for brazing steel

Wrought Copper and Copper-Base Alloys

“…He concluded that the effect is less than might be anticipated for such materials as copper, bronze, manganese bronze, red brass, silicon bronze, aluminum bronze, brass, phosphor bronze, tough pitch copper, Monel, various alloys of steel, and certain stainless steels. The use of gaseous fluxes for brazing steel has been studied by Edson, Paquette, and Newell (43). Such fluxes may prove useful for critical applications where conventional fluxes are not applicable; boron trifluoride is shown to be attractive.…”
