It is a flux intended for brassing Copper/Brass/Steel and Stainless Steel with all silver alloys with a great pickling powder. The waste of flux are eliminated by thermal shock (dipping in cold water) or by brushing.
At use, the powder Flux-it 340 allows a very good adhesion even on a vertical surface. There are neither retention and nor profusion, so it allows a good stability in the brazing during melting.
Dry powder of calibrated granulometry without any boric acid or soluble borates.
The powder Flux-it is advised for the brazing and the soudo-brazing by oxy-acetylenic flame or by gas at temperatures between 650–750° C
The powder Flux-it 340 is used in powder or it can be mixed with water in order to form a paste (80/20 flux/water) or it can be used by diping the filler metal stick headed in the powder.
