3. Introduction
Aluminum is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal.
Aluminum one of the key engineering materials of our time.

4. Physical Propties of Aluminum
• Is strong, malleable and has a low density.
Is resistant to corrosion.
•Electrical conductivity and resistivity
• Non-magnetic property
• Thermal conductivity
• Corrosion resistance
• Thermal expansion
• Melting temperature
• Specific and latent heats

5. CHIMECAL propties of aluminum
Aluminium reacts so readily with oxygen that you never naturally find it in its pure form.
Compounds of Aluminium exist in huge quantities in Earth's crust as an ore (raw rocky material) called bauxite.
•Pure aluminum reacts rapidly with air to form a rustproof protective layer of aluminum oxide.
Dissolves in water in specific forms.
Malleable and clouds

7. HOW THE ALIMUNUAM AVAILABALE IN NATURAL
There in the earth's crust after oxygen and silicon by the amount of 8.3%.
Metal aluminum does not exist in nature in pure form free.
It is often associated with oxygen in the form of oxides or silicates.
There are several forms of nature on the most important aluminum silicate Al2 (SiO3) 3 and Al2O3.XH2O bauxite and cry lite Na3AlF6
