| Aluminium is present in more than 270 minerals. |
| It is the most abundant mineral on Earth after oxygen and silicon. |
| It is also the most abundant metal found naturally on Earth. |
| Aluminium is globally the most used metal that does not contain iron. |
| Aluminium is almost always used as an alloy, even if the aluminium content is as high as 99%. |
| The most commonly used elements to combine with aluminium to create an alloy are zinc, copper, silicon, magnesium, and manganese. |
| Aluminium salts do not serve any known purpose in plant or animal life. |
| It is, however, not highly toxic to living organisms in small amounts. |
| Aluminium reflects about 92% of visible light. |
| It reflects about 98% of infrared rays. |
| Its density and stiffness are about a third of the density and stiffness of steel. |
| There are many recognized isotopes of aluminium, but only two are found in nature. |
| Because of aluminium's high likelihood of binding with oxygen, pure aluminium is almost never found in nature. |
| Aluminium's silicates or oxides are more likely to be found naturally. |
| Aluminium is extremely difficult to isolate from minerals because it is extremely reactive. |
| The ores that contain aluminium have a very high melting point, making extraction problematic. |
| Australia is the leading producer of the world's aluminium. |
| Aluminium is potentially fully recyclable. |
| Recycling aluminium requires only five percent of the energy that extracting it from ore requires. |
| The byproduct of aluminium production and recycling is called white dross. |
| White dross can be highly combustible, but serves purposes in concrete and asphalt production. |
