WHAT IS FLUX?
This is the most commonly asked question we receive from people who have never worked with fluxes.
FLUX: A chemical composition critical to the heat joining methods of soldering, brazing, and welding that:
A substance that aids, induces, or otherwise actively participates in fusing or flowing, as:
- A substance applied to a surface to be joined by welding, soldering, or brazing to facilitate the flowing of solder and prevent formation of oxides.
- A mineral added to the metals in a furnace to promote fusing or to prevent the formation of oxides.
- An additive that improves the flow of plastics during fabrication.
- A readily fusible glass or enamel used as a base in ceramic work.
