What Is the Chemical Formula of Aluminium Fluoride?

The chemical formula for aluminum fluoride is AlF3. This compound has three atoms of fluorine for every atom of aluminum. Manufacturers use aluminum fluoride to produce sheets of aluminum metal.

Aluminum fluoride, also called aluminum (III) fluoride or aluminum trifluoride, is a white solid with a boiling point of 1275 C. This compound is made up of 67.87 percent fluorine and 32.13 percent aluminum. Aluminum fluoride may be contaminated with small amounts of iron, silicon, chromium, magnesium or nickel, according to PubChem Compound. Aluminum metal manufacturers use this compound to reduce the melting point of several electrolytes, which increases production efficiency. Manufacturers also use aluminum fluoride to remove magnesium from pieces of aluminum scrap metal.
