- •
Corrosion of aluminum alloy 2024 exposed to the fungus Aspergillus niger was studied.
- •
The presence of A. niger accelerated the corrosion of AA 2024.
- •
The corrosion was mainly caused by the oxalic acid produced by A. niger.
- •
A. niger caused aluminum depletion accompanied with copper enrichment.
- •
Micro pits and pit clusters resulted in AA 2024 when it was exposed to A. niger.
