It's useful because it can be easily shaped or cast into sheets or parts, it is resistant to corrosion and it is lightweight. That's because aluminum atoms have about one third the number of protons and neutrons crammed into their centers than iron or copper, making aluminum much less dense.

Aluminum is used to make pots and pans, aircraft, soda cans, power lines, window frames, bicycles and railway cars.

Most traditional combinations of aluminum and other metals, called alloys, are not as strong as steel, which itself is an alloy of iron and carbon. In the past, the process of producing aluminum alloys strong enough to be used in body parts that can move a heavy load has been more expensive than steel.
