Corrosion of aluminum

Corrosion is generally expected only from ferrous metals such as iron or steel. But aluminum can also corrode. Only the extensive corrosion of aluminum is rare. It always occurs only when the action of the oxide layer is removed in a strongly acidic or alkaline environment. What types of corrosion can occur with aluminum, you can read here.

Possible corrosion of aluminum

Aluminum protects itself effectively against surface corrosion and major damage through its oxide layer. Depending on the alloy and the condition of the workpiece, however, other types of corrosion of aluminum may occur:

  • pitting
  • stress
  • intergranular corrosion and layer corrosion

Tips & Tricks

Also with metal pairings one should be careful - here under certain circumstances contact corrosion is possible.
