Aluminium Fluoride

Mainchin Chemicals, Trusted Global Partner & One Stop Solution for Aluminium Fluoride LBD and HBD
Top Global Supplier of Aluminium Fluoride LBD and HBD

Mainchin Chemicals is one of the leading global supplier of Aluminium Fluoride (AlF3) in both LBD and HBD grades. We are one Stop Shop for Aluminium Fluoride (LBD and HBD).

Aluminium Fluoride (AlF3) – LBD and HBD is one of the important key material and used as flux in the production of primary Aluminium metal and manufactured through dry process using Fluorspar and Aluminium Hydrate as a raw material. In this process, high density Aluminium fluoride is produced which is preferred for modern Aluminium smelters in world. This is of critical importance as it lowers electricity consumption during the smelting process. Consequently, primary Aluminium Smelters are the biggest users of Aluminium Fluoride.

It is also used in few locations as an additive to Aluminium Metal crucible before entering into the cast house furnaces to reduce alkali metals like Sodium and/or Lithium, and Ceramic industries.

Our Aluminium Fluoride can improve the quality of aluminium ingots and reduce production costs because of their high fluorine content and low impurity content.

We can supply Aluminium Fluoride as per customers requirement and the product specifications given below for HBD and LBD grade is for reference and further customisation can be possible.

Aluminium fluoride is an important additive for the production of aluminium by electrolysis. Together with cryolite, it lowers the melting point to below 1000 °C and increases the conductivity of the solution. It is into this molten salt that aluminium oxide is dissolved and then electrolyzed to give bulk Al metal.

  • Aluminium Industry – used as a flux in reducing the melting point of Alumina during the electrolytic process of producing Aluminium. It is also used as an additive to Aluminium Metal crucible before entering into the cast house furnaces to reduce alkali metals like Sodium and/or Lithium
  • Alcohol Production – used as an inhibitor of by-fermentation
  • Metal Welding – it is used for welding fluids and optical lenses
  • It is used as catalyst for organic synthesis and raw material for artificial cryolite
  • Ceramics Industry – as flux for ceramic glaze and enamel glaze, and a component of glaze powder
  • Non-Ferrous Industry – as a flux
  • In the aluminium electrolysis industry, it is used to reduce the melting temperature of the electrolyte and increase the conductivity of the electrolyte
  • as well as an inhibitor for side-fermentation in essential oil production.
  • Fluoroaluminate Glasses – Together with zirconium fluoride, aluminium fluoride is an ingredient for the production
  • It is also used to inhibit fermentation.

Aluminium Fluoride – used as a low-index optical thin film, particularly when far UV transparency is required. Its deposition by physical vapor deposition, particularly by evaporation, is favourable.
