What are
the Properties of Aluminum? Definition of Aluminum
What is the definition of
Aluminum? It is a silvery-white, ductile metallic
element, the most abundant in the earth's crust but found only in combination,
chiefly in bauxite. Having good conductive and thermal properties, it is used to
form many hard, light, corrosion-resistant alloys. The
Physical and
Chemical Properties are the
characteristics of a substance, like Aluminum, which distinguishes it from any
other substance. Most common substances exist as
States of Matter as solids, liquids, gases and plasma. Refer to the article on
Aluminium for additional information and facts about this substance.

- What are the Physical Properties of Aluminum?
What are the Physical
Properties of Aluminium? The Physical properties of Aluminum are the characteristics
that can be observed without changing the substance into another
substance. Physical properties are usually those that can be observed using our
senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Aluminum are as follows:
|
What are the Physical Properties of Aluminum? |
| Color |
Silvery-white
with a bluish tint |
|
Hardness |
The pure metal is soft, but
it becomes strong and hard when alloyed |
|
Ductility |
It can be beaten into
extremely thin sheets |
|
Malleability |
Capable of being shaped or bent |
|
Conductivity |
Good electrical and heat conductors |
| Corrosion |
Resists corrosion by the
formation of a self-protecting oxide coating |
Aluminum Properties - What are the Chemical Properties of Aluminum?
What are the Chemical
Properties of Aluminum?
They are the characteristics that
determine how it will react with other substances or change from
one substance to another. The better we know the nature of the substance the
better we are able to understand it. Chemical properties are only observable during a
chemical reaction. Reactions to substances may be brought
about by changes brought about by burning, rusting, heating, exploding, tarnishing
etc. The Chemical
Properties of Aluminum are as follows:
|
What are the Chemical Properties of Aluminum? |
| Chemical
Formula |
Al |
|
Occurrence |
Occurs only as
a compound, principally in bauxite |
|
Oxidation |
In moist air, it combines
slowly with oxygen to form aluminum oxide |
|
Reactivity with acids |
Reacts with many hot acids |
|
Reactivity with water |
Reacts quickly with hot
water |
|
Reactivity with alkalis |
It reacts with Alkalis such
as Sodium hydroxide and limewater |
| Compounds |
A mixture of aluminum,
oxygen and other elements produces Bauxite
Bauxite is an aluminium ore and is the
main source of aluminium |
|
Alloys |
When
combined with elements such as copper, silicon, or magnesium it
forms alloys of great strength |
