Interesting Facts About Aluminum

1) Aluminum is a chemical element, symbol Al and atomic number 13.

2) It is a non-ferromagnetic metal.

3) It is the third most common element found in the Earth’s crust.

4) Aluminum compounds form 8% of the Earth’s crust and are present in most rocks, vegetation, and animals.

5) In its natural state, it is found in many silicates (Feldspars, plagioclase, and Micas).

6) This metal is extracted only from the mineral known with the name of bauxite, by transformation first in alumina and then in metallic aluminum by electrolysis.

7) This metal has a combination of properties that make it very useful in materials engineerings, such as its low density (2700 kg/m³) and its high corrosion resistance.

8) Means of suitable alloys can significantly increase the mechanical strength (up to 690 MPa).

9) It is an excellent conductor of electricity and heat, and it is very cheap.

10) It is the most used metal in the world, just behind the steel.

11) It was isolated for the first time in 1825 by the Danish physicist H. C. Oersted.

12) The main drawback to obtaining it lies in the high amount of electrical energy required by its production. This problem is compensated for its low recycling cost, extended shelf life, and price stability.
