Aluminium Facts

Aluminium Facts
Aluminium (Al), or aluminum, is a silver, soft metal with an atomic number of thirteen and thirteen protons in the nucleus. It constitutes about eight percent of the Earth's land mass.
Interesting Aluminium Facts:
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.
