Sure Flo Fluxes

For low temperature brazing, Sure Flo Flux is a creamy and smooth composition that provides excellent adhesion to parts. Its consistent blend will not spatter or run during a rapid heating cycle (like induction processes). Sure Flo Flux has excellent fluxing action and oxide removal and will not crystallize under normal conditions.

Sure Flo Black - Paste
Similar as Handy B-1, Sure Flo Black can be used for brazing high chromium stainless steels, tungsten and chromium carbides, and molybdenum alloys.
