Aluminum | Chemical elements

Aluminum, also known as aluminium, was discovered by Hans Christian Oersted in 1825 and its name comes from the Latin word alumen. Aluminum is mainly obtained from bauxite.

Top 18 interesting facts about Aluminum

  1. Aluminum is the most abundant metal and the third abundant element in the Earth crust.
  2. Aluminum is silver and soft.
  3. Aluminum is very reactive so it can be found naturally only in minerals, mainly in bauxite.
  4. Aluminum has a very low density, making it a very light metal, and it is very resistant to corrosion.
  5. Aluminum has a huge role in aerospace and transportation industries.
  6. Aluminum is a great structural material due to its light weight and strength (in aluminum alloys).
  7. Although it is a metal, Aluminum is nonmagnetic.
  8. Aluminum is a good thermal and electrical conductor.
  9. Aluminum is a very corrosion resistant metal due to the fact that it forms a thin layer of oxide when it is expose to air preventing further corrosion.
  10. Aluminum has many isotopes but only two of them occur naturally; Al-27 and Al-26.
  11. Aluminum is created in large stars or supernovae by the fusion of Hydrogen and Magnesium.
  12. Aluminum can be recycled without any lose of its original properties.
  13. Aluminum is almost always used as an alloy in combination with other metals (copper, zinc, magnesium etc).
  14. The main use of Aluminum is in the following areas: aerospace, transportation, packaging, construction, cooking utensils, lighting poles, consumer electronics, pyrotechnics etc.
  15. Aluminum is a nontoxic metal.
  16. After iron, aluminum is the second most used metal.
  17. Aluminum production requires a great amount of energy making recycling aluminum a cheap process because it requires only 5% of the amount of energy.
  18. Aluminum melting point is at 660.37 °C (933.52 K, 1220.666 °F) and boiling point at 2467.0 °C (2740.15 K, 4472.6 °F).
