Aluminum bromide belongs as the main component to xylene electrolytes for electric precipitation of aluminum coatings. The anhydrous aluminum bromide is used in organic synthesis, in particular, in the alkylation reaction or Friedel-Crafts reaction by analogy with aluminum chloride.
Aluminum is the most abundant metal and the third most abundant element, after oxygen and silicon, in the earth's crust. It is widely distributed and constitutes approximately 8 percent of the earth's surface layer. However, aluminum is a very reactive element and is never found as the free metal in nature.
