Uses #1: Construction Purposes
Aluminium is a light, strong metal and has good electrical conductivity.
Increasingly it is being used for construction purposes.

Uses #2: Aircraft and Vehicles
Some modern cars was built out of aluminium.
For use in aeroplanes, it is usually alloyed with other metals such as copper.
9
Uses #3: Overhead Power Lines
Its low density and good conductivity have led to its use in overhead power lines.
10
Uses #4: Food Packaging
Aluminium is protected from corrosion by the stable layer of aluminium oxide that forms on its surface. This protective layer stops the aluminium (a reactive metal) from reacting.
This makes aluminium foil containers ideal for food packaging.
11
Uses #5: Window Frame
Aluminium is also used for external structures such as window frames because they resist weathering.
