Aluminum Trifluoride A Flux In Aluminum Alloy Casting

Aluminium Fluoride AlF3 Application: 

1. Its mainly used as a flux in the aluminum smelting by fused-salt electrolysis; 

2. An opalizer in the manufacture of enamel; 

3. An opacifier and auxiliary solvent of glass and enamel; 

4. An insecticide of crops;

5. A flux in aluminum alloy casting; 

6.  In the production of ferrous alloy and effervescing steel; 

7.  As well as a wear-resistant filler for Resin and rubber-boned Abrasive wheels.

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.
