Fluoride-Free” Drossing Fluxes – The New Frontier of Safety and Sustainability in Foundry

In today’s modern foundry landscape, the pursuit of high-performance solutions increasingly goes hand-in-hand with the need to reduce environmental impact and ensure safe working conditions. To meet these demands, Jodovit has developed a complete line of granular fluoride-free fluxes, ideal for cleaning, covering, and maintaining the molten bath in aluminum alloy processing.

Why choose a fluoride-free flux?
Traditional fluxes containing fluorides may release toxic substances (such as hydrofluoric acid) during application, posing potential health and environmental risks. Our fluoride-free products offer several advantages:

• No emission of HF or other corrosive gases
• Lower fume and dust generation during use
• Dry, lightweight dross that is easy to remove and has low metal content
• Extended crucible and refractory life
• Full compliance with REACH directives and current environmental regulations

SCOREX Line – Fluoride-Free Granular Fluxes

SCOREX GR FF 4
Covering and cleaning flux for aluminum alloys (excluding Al-Mg), designed for refineries and high-productivity plants.

• Versatile use: applicable during transfer or directly on the molten surface
• Dry, metal-free dross: easy to remove
• Optimized for automation: consistent grain size (1–4 mm >90%) for automatic degassing systems
• Low consumption: effective even at reduced dosage (0.05–0.25% of metal mass)
• Low density: ~1.0 g/cm³
• Working temperature: ≥ 720°C
