What do we use it for?

What is this?

It is the most abundant metal since it constitutes around 8% of our planet's crust.It is very flexible and, therefore, is currently the second most used metal after steel. It is also very ductile and malleable, has low density, is a good conductor of heat and electricity, and is very resistant to corrosion.

Where do we get it from?

Aluminum is obtained from a mineral called bauxite. It occurs in various chemical forms in most rocks and soils, in vegetation and is found naturally in water currents and in dust particles in the air.

What do we use it for?

We are using the aluminium for make cans, electrical cables, portable ladders, doors and window frames, radiators, pots and pans, airplanes, the outside of walls and roofs of homes aluminum foil and many other objects.

Repercussions on nature:

The pollution generated by the aluminum industry is worrying because it produces millions of tons of greenhouse gases per year, such as carbon dioxide, and gases that are also present in acid rain, such as sulfur oxide and nitrogen oxide.
