Silver Brazing Fluxes Oxiflux® series for Tungsten Carbides

Flux selection is determined by the base metal and the filler metal alloys working temperature. The working temperature and melting range of the filler alloy must match the flux's active range.

Oxiflux® Flux Powder
	Recommended for:	Description and Flux characteristics:	General information:
	Used for brazing of tungsten carbide, tungsten carbide backed PCD and certain grades of cast iron. Suitable for flame and induction heating brazing. Activity range: 570 - 870°C.	Oxiflux ® is a special purpose silver brazing white powder flux. Perfect wetting action. Wide active range. High activity medium to long life flux.	Based on specification: AWS A5.31M: TYPE FB3-F. For use with BAg (High to medium silver brazing alloys containing nickel and manganese) group alloys.
