I was trying to find the answer to this same question and it is not available online. Or atleast it is not easy to find the information because its a rare (specific) area of science.
In air aluminium is coated with a protective film of aluminium oxide.
Oxidation: 4 Al + 3 O2 --> 2 Al2O3
Corrosion is a chemical process.
There are three factors... 1) Temperature 2) Pressure 3) The presence of Oxygen
No, corrosion of aluminum metal is a chemical process. It occurs when aluminum reacts with oxygen in the presence of moisture, forming a layer of aluminum oxide on the surface. This chemical reaction leads to the degradation of the metal over time.

Aluminum cans are made almost entirely of aluminum. The interiors are made of aluminum oxide, which is highly resistant to corrosion. This is a compound, not a mixture.

Pitting is the most common type of corrosion found on aluminum and magnesium alloys.
5052 H32 aluminum. its an Al/Mg allow resistant to corrosion.
Aluminum corrodes rapidly on its exposed surface, but unlike the rust on iron which catalyzes more corrosion, this corrosion layer is protective and once it is thick enough corrosion stops. After that aluminum can last almost forever, unless the layer is damaged.
It is normal that using materials which are not corroded corrosion is avoided.
When exposed to air the surface of a piece of aluminum will oxidize and form a coating of aluminum oxide, known in its mineral form as corundum. Aluminum oxide is one of the hardest substances on Earth and so protects the aluminum from further oxidation. It is possible to get aluminum to corrode. Mercury will prevent the oxide from forming a protective coating.
Because aluminum is very strong and very light and it is resistant to corrosion
