Aluminum: The Element

Properties-
Aluminum is the 13 element on the periodic table. It has high
malleability and ductility, high electrical conductivity, high thermal
conductivity, and high resistance to corrosion. Some useful alloys that are
useful are aluminum bronze, alnico, and aluminum alloy, ect. Aluminum is
strongly electropositive and extremely reactive. In contact with air,
aluminum instantly becomes covered with a rough transparent layer of
aluminum oxide.

History-

Uses-

The given volume of aluminum weighs less than one-third than steel. Its
high strength to weight ratio makes it very useful. We use it from foils to
cans, to space shuttles. This element is very, very useful and is
recyclable. We use aluminum for conductors as well. We use it to weld
hardware together because of their great conductability.

Since the early 1800's we have seen aluminum as a great metal with
countless uses. But we can't make all the aluminum we need, although there
is a lot on Earth, we have a certain amount that we can run out of if we
don't re-use and ...
