Applications:

Aluminum fluoride is an important additive for the production of aluminum 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 aluminum oxide is dissolved and then electrolyzed to give bulk Al metal

Aluminum fluoride is an ingredient for the production of fluoro aluminate glasses.

It is also used to inhibit fermentation.

It is a sputtering target for preparation of low index films.
