Aluminium has low density
(is light), is strong
and is corrosion-resistant.
- Lightweight (low density).
- It can be bent and shaped into, say, car body panels.
- It's strong and rigid when required.
- It doesn't corrode due to a protective layer of oxide which always quickly covers it.
- It's a good conductor of heat and electricity.
It's not as strong as steel
, however, and is a bit more expensive.
- Car body panels.
- Drink cans. Tin-plated steel ones can rust if damaged.
- Greenhouses and window frames.
- Power cables.
