Before chemists developed inexpensive ways to produce pure aluminum, it was considered a somewhat precious metal. In fact, in 1855, a bar of pure aluminum metal was displayed at the Paris Exposition. It was placed next to the French crown jewels!

Aluminum is an excellent conductor of electricity.

The abundance of aluminum in the Earth's crust is estimated to be about 8.8 percent. It occurs in many different minerals.

Bauxite, a complicated mixture of compounds consisting of aluminum, oxygen, and other elements, is the primary commercial source for aluminum alloy.

Large reserves of bauxite are found in Australia, Brazil, Guinea, Jamaica,Russia, and the United States. The largest producer of aluminum metal is the United States; states that produce the most aluminum are Montana, Oregon, Washington, Kentucky, North Carolina, South Carolina, and Tennessee.
