Aluminum is a solid, not usually found by itself in nature. Aluminum is very conductive, meaning it conductucts heat and electricity very well. It is also vey Ductile and malleable, which allows the element to be bent or hammered into a shape (electrical wire). It is remarkable for its ability to resist corrosion due to the phenomenon of passivation (when a material becomes passive, or becomes less affected by environmental factors like air or water.
Aluminum was discovered in 1825 by a Danish chemist and physicists teacher Hans Christian Dersted. He developed a way to extract small amounts of aluminum from alum by having anhydrous aluminum chloride react with potassium amalgam. This produces a big chunk of metal with properties similar to the likes of tin.
Aluminum is found all over the world, but mostly in Ghana, Indonesia, and Jamaica but it is found only in chemical compounds with other elements. These elements include sulfur, silicon, and oxygen. Pure metallic aluminum can be economically produced from aluminum oxide ore.
Aluminum can easily be recycled because the surface quickly oxidizes to form an invisible barrier to corrosion. Aluminum is one of the most abundant element in the world and the most abundant metal in the earth’s crust. Without it the crust and everything above it wouldn’t exist.

Alluminum does nothing for the human body at all.. why do we need this element?
Long lasting uptakes of significant concentrations of aluminum can lead to serious health effects, such as:
- Damage to the central nervous system
- Dementia
- Loss of memory
- Listlessness
- Severe trembl

Would the world be a different place without aluminum? what makes it so important?
it makes up most of the crust.
Hey, you spelled aluminum wrong...
quit asking google for help
if you are exposed to too much aluminum, you can get aluminum toxicity.
learn how to use spell check and i will stop using google
Hey, you spelled aluminum wrong...
Much pollutuion is caused by aluminum cans and plants.
not only spelling aluminum wrong... Isnt it copper that is used for wires? and the only good thing about aluminum is baseball bats..
Plastic wrap is better than aluminum foil.... Nuff said. We don't need you...
Not all vehicles are equipped with all or any of these aluminum parts, however....
Wow, without a aluminum we will not have any form of transportation. GASP aluminum is the only metal possible to create cars. How does aluminum benefit the body in a positive way?
CARS are one of the biggest causes of DEATH. Aluminum is a KILLER
