Aluminium oxide is liable for resistance of metallic aluminium to weathering. Metallic aluminium may be very reactive with atmospheric oxygen, and a thin passivation layer of alumina (four nm thickness) forms in about 100 picoseconds on any exposed aluminium floor.[five] This layer safeguards the metallic from even more oxidation.
