1. -Density
-Corrosion Resistance
-Electrical and Thermal Conductivity
-Light and Heat Reflectivity
- Ductility

2. The density of aluminium
 The density of aluminium is 2,7 g/cm3 ,around
one third that of steel.
 Used advantageously in applications where high
strength and low weight are required.
=>> Greater in load capacity and reduced fuel
consumption.

3. Corrosion Resistance of Aluminium
-When the surface of a luminium metal is
exposed to air, a protective oxide coating
forms almost instantaneously.
-If the oxide becomes scratched and
aluminium metal exposed, more oxide
is formed and the protected layer
renewed.
-This oxide layer is corrosion
resistant and can be further
enhanced with surface treatments
such as anodising.

4. Electrical and Thermal Conductivity of
Aluminium
Resistivity: 2,82×10−8 Ωm
Thermal Conductivity : 202.4 W/mK
The great advantage of a luminium is that by
weight, the conductivity of a luminium is
around twice that of copper.
=>> Aluminium is an excellent conductor
of both heat and electricity.

5. Light and Heat Reflectivity of Aluminium
-Aluminium is a good reflector of both
visible light and heat
-Electrical Resistivity : Low 2.65 x 10 -8
Ohm metres
=> Aluminium has slow electrical
resistivity and therefore has high
electrical conductivity
-Reflectivity : High 71% unpolished and
when polished: 97%
=> Aluminium is extremely reflective,
when polished (some sources say) it is
the most reflective material, for this
reason it is now frequently used in lights.

6. High ductility
- Aluminium is easy when plastic
deformation , spinning, wire and rolled into
sheets,foil, tape, film (foil), pressed into
bars flowing with the contour length (profile) compl
ex very different issue.
=>> Summary: Aluminium has a unique set of properties
that make it so essential to the modern world. It is
ductile , strong (in alloys), lightweight, highly
conductive, and extremely reflective.

7. APPLICATION AND USE OF ALUMINIUM
 Electrical Conductors
 Material of construction for Transport
 Packaging
 Building and Architecture
 Foils
 Miscellaneous Applications

8. Electrical Conductors
- Aluminium alloys have a
conductivity averaging 62% of the
International Annealed Copper
Standard (IACS) but, because of its
density, it can carry more than twice
as much electricity as an equivalent
weight of copper.
- A very large proportion of overhead,
high voltage, power lines utilise
aluminium rather than copper as the
conductor on weight grounds.

9. Material of construction for Transport
-The transport and automotive
industry is the fastest-growing
market segment for aluminium
suppliers.
-Various alloys of aluminium
are now also used in passenger
and freight rail cars,
commercial vehicles, military
vehicles, ships & boats, buses
& coaches, bicycles and
increasingly in motor cars.

10. Packaging
-The successful use of the 1000 series
alloys as foil for food wrapping and for
containers utilises their good corrosion
resistance and barrier properties
against UV light, moisture and odour.
-The most significant use of aluminium
in packaging has been in the
production of beverage cans which
incorporate the easy open ring pull' in
the lid.

12. Foils
 Aluminium is produced in
commercial foils as thin as
0.0065 mm (or 6.5 µm). Material
thicker than 0.2mm is called
sheet or strip.

14. SUMMARY
 Aluminium is the world's most abundant metal
and verry important in our life.
 By utilising various combinations of its
advantageous properties such as strength,
lightness, corrosion resistance, recyclability and
formability, a luminiu m is being employed in an
ever-increasing number of applications.
