aluminum

Aluminum is a relatively light weight type of silver-colored metal. Most soda cans are made out of aluminum.

There is more aluminum in the earth's crust than any other kind of metal, and because it is so sturdy, pliable, and light, it's used to make all kinds of things. Airplane parts, aluminum foil, metal baseball bats, bicycles, and some power lines are just a few of the everyday objects that are made at least in part from aluminum. The name is based on alumina, or aluminum oxide, with a Latin root of alumen, "bitter salt."
