  3. ◆ Aluminum is very light, only one third of the weight of steel and copper.
  4. ◆ It is a soft metal with only 150 years of use, making it one of the youngest metals. By comparison, copper is more than 9,000 years old.
  5. ◆ It was first extracted in 1825 by the Danish chemist Hans Christian Oersted.
  6. ◆ The melting point is 660 degrees Celsius and the boiling point is 2519 degrees Celsius.
  7. ◆ Aluminum is corrosion-resistant, extremely durable, and can be recycled almost indefinitely.
  8. ◆ Aluminum is a very active element that can react with oxygen. However, the oxidation byproduct is not rust, but a dense film of aluminum oxide that protects its interior from further corrosion.
  9. ◆ In 2012, aluminum production for food and beverage packaging alone exceeded 1.9 million tons.
  10. ◆ At one point in the 19th century, aluminum was considered rarer than gold because of its expensive and complicated extraction process.
