Aluminium oxide is accountable for resistance of metallic aluminium to weathering. Metallic aluminium is extremely reactive with atmospheric oxygen, and a skinny passivation layer of alumina (4 nm thickness) sorts in about 100 picoseconds on any uncovered aluminium area.[5] This layer shields the steel from further oxidation.
