Harris SSWF1 Stay Silv Brazing Flux, 1 lb. Jar, White

This works well for silver soldering brass to brass, stainless to brass, and stainless to stainless. There's a bit of a learning curve, but when you get the temperature high enough, the Flux pulls the solder into the joint and creates a strong bond. Silver solder requires more heat, which could burn off regular solder, but this stuff stays in place. Notes: - I learned from an online video that if you melt solder and let it pool around a joint, it will flow into the space with flux applied as the temperature increases to the sweet spot. - Only put flux where you need it, as the solder will be drawn to it. - The parts must be cleaned well. - Take your time bringing it up to temperature. If you blast it, carbon deposits can accumulate and interfere with bonding. - I tried this with Mapp gas and propane; most joints easily get hot enough with propane. - The flux leaves a crusty residue that can be removed after it cools. I use a wire brush. Overall a great product!

I work in copper and at brazing temp no need for a flux But my AI talked me into trying it because of the ability to help holed the copper Brazing once turned into round solder balls in place also reduces the cleanup after

Great product. Just love it.

I couldn’t get the solder to stick to the stainless with this stuff. Maybe it’s me. Update: This is brazing flux a propane torch is not hot enough.

This is one of the best fluxes for silver brazing. You just need a thin film, and the silver will flow like water. Used sparingly there isn't much to cleanup, but if there is a little black crust it can be cleared up with a squirt of water or a rub with a wet rag. It does settle over time, so if you don't use it often there may be need for stirring the liquid back into the paste. Be sure to stock up on silver brazing rods before the price gets stupider.

This product works well
