What does aluminum look like?

Aluminum is a dull silvery metal that has a bluish tint. It is ductile and malleable, and it is a good conductor of heat and electricity.

Aluminum is the third most common element in the Earth's crust and the most abundant metal, making up 8 percent of the Earth. Aluminum cannot be found naturally as a pure metal; instead, it is found in compounds that can be difficult to separate. Aluminum metal reacts with water and air to form oxides and hydroxides. It is the second-most-used metal in the world, used to make cars, machinery and electrical tools. It is also used in cans and foil and can be recycled.
