Corrosion: Undesirable Redox Reactions
- Iron is not the only metal that undergoes oxidation.
- Most other metals, such as copper and aluminum, also undergo oxidation.
- However, the oxides of copper and aluminum do not flake off as iron oxide does.
- When aluminum oxidizes, the aluminum oxide actually forms a tough, clear coating on the underlying metal.
- This coating protects the underlying metal from further oxidation.
