i am a scientist for NASA and we have found that:
- Aluminum is very light, so it is good for making things like airplanes and soda cans, things people don't or can't have being too heavy.
- Iron is strong and cheaper than steel, though also weaker than steel, but for things that don't have to stand the test of time, iron is a good candidate.
therefore, they are the most commonly used metals worldwide because they are the most practical metals for popular, everyday products.
we use aluminum in our space shuttles and iron bolts to secure the seats and doors and windows, etc.
