This is the most commonly asked question we receive from people who have never worked with fluxes. Cos Flux is a nonflammable flux for use in battery fabrication. It’s a chemical composition critical to the heat joining methods of soldering, brazing, and welding. This water-based flux offers a wide process window, contains no chlorides or heavy metals to effect long term performance, and is environmentally safe. Furthermore it provides consistent metallurgical fusing for all lead battery alloys when a water-based flux is needed.
Chemically: 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.
Battery Flux Features:
- Highly active
- Excellent flow
- Low Residue
