Frequently Asked Questions

For brazing and soldering operations, flux is required to facilitate the wetting of the filler metal, dissolve metal oxides that form during the heating process, and protect the surface from oxidation.

Silver brazing is more resistant to high heat than soldering with soft soldering. It is therefore stronger and allows for better aging. The joint is stronger and ductile.

Flux requirement will depend on:   

• Battery type (EFB, AGM, VRLA…)  
• Lug alloys,
• Flux application method,
• COS Materials parts.

Indeed, PPE is required. Before use, always refer to the Safety Data Sheet.

• 1 / its performance on soldering metals;
• 2 / its operating temperature;
• 3 / its form (gel, liquid, paste or powder);
• 4/ How easy to clean residue.

Despite their ease of use, mineral fluxes have a strong environmental impact. This is why organic fluxes have been developed: 

1. no heavy metals such as zinc, 
2. easily derivable into biodegradable compounds,   
3. non-polluting residues, 
4. vapours that are less agressive to workers.
