SSWF1 - Harris Stay-Silv White Silver Brazing Flux Paste, 1 lb

Smooth Application for Perfect Silver Brazing

When you are out in the field or in the shop working on a critical repair, you need a flux that behaves predictably and helps you get the job done right the first time. Harris Stay-Silv® White Brazing Flux is the go-to choice for welders and HVAC technicians needing a reliable, all-purpose flux for silver soldering. This 1 lb jar contains a smooth, white paste that is easy to brush on and stays where you put it, giving you even coverage exactly where you need the solder to flow. It takes the guesswork out of prep by effectively cleaning the metal surface as you heat it up.

This flux is active between 1050°F and 1600°F, which is the sweet spot for most silver brazing tasks. As you apply heat, the flux turns into a clear liquid that dissolves oxides on the metal surface, paving the way for your silver solder to penetrate deep into the joint. It works exceptionally well on copper, brass, steel, stainless steel, and bronze. Whether you are brazing HVAC lines, repairing cast iron parts, or fabricating custom steel components, Stay-Silv® White protects the base metal from burning and ensures a strong, leak-proof bond. It is not for use on aluminum, but for almost everything else in your ferrous and non-ferrous arsenal, it is the standard.

Using the right flux is half the battle in brazing. Harris has formulated this paste to provide excellent protection during the heating cycle, preventing that annoying black scale from forming before you are ready to add filler. Once you are done, the residue cleans up relatively easily, leaving you with a professional-looking joint. Don't risk your reputation on cheap flux; stick with the proven performance of Harris Stay-Silv® to ensure your silver brazing alloys flow smoothly and bond securely every time.
