Flux Basics | What is Flux

Just as the flux itself spreads onto the surface, the solder alloy must also. A good flux will lower the surface tension between the metal and the molten solder. Before, the surfactant was a wetting agent to help the flux spread. Now the flux is a wetting agent for the solder alloy. The better a flux is at this, the better it performs in ...

Flux (metallurgy) - Wikipedia

In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were carbonate of soda, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.
