Why does aluminium go white?
A common problem with aluminium is water staining. Water staining is generally a white powdery substance on the surface of the aluminium but depending on the alloy or amount of oxidation it may have an iridescent appearance. It is caused by the entrapment of moisture between the surfaces of closely packed aluminium.
Can pitting be removed from aluminum?

What is the white powder on aluminum?
Aluminum oxide appears as a powdery white or dull gray coating. As oxidation occurs, it hardens and creates a protective layer over the newly exposed areas of corroded aluminum.
What metal turns white when corroded?
zinc materialsWhite rust is a white, chalky substance that can form on the surface of zinc materials, like galvanized steel. White rust can form when zinc is exposed to hydrogen and oxygen. This combination creates a zinc hydroxide, as opposed to the iron oxide which is common form of rust.
What happens when you scratch aluminum oxide?
Aluminum Corrosion. Scratching this oxide skin exposes bare metal, and the process begins again. It won’t eat the metal away though, except under two conditions. First, if chlorides or sulfides are around they’ll attack the aluminum oxide layer. Chlorides are compounds of chlorine.
Why does aluminum oxidize faster than steel?
Aluminum oxidation happens faster than that of steel, because aluminum has a really strong affinity for oxygen. Rather than flaking though, aluminum oxide just forms a hard, whitish-colored surface skin. When all the aluminum atoms have bonded with oxygen the oxidation process stops.
What is rusting metal?
Rusting is a specialized form of corrosion that only iron and steel go through. Rust is when the iron oxidizes and flakes off. It’s accelerated by moisture. Flaking exposes fresh metal beneath, which in turn oxidizes and flakes. Aluminum oxidation happens faster than that of steel, because aluminum has a really strong affinity for oxygen.

What is the difference between rust and corrosion?
(Gold is one notable exception.) Corrosion starts with oxidation, where atoms of metal link up with oxygen, followed by a gradual , or not so gradual , breakdown. Rusting is a specialized form of corrosion that only iron and steel go through.
Which is better, aluminum or aluminum?
Spend too long in damp environments and you’ll find reddish brown flakes lifting off the surface. Aluminum would be better because its much lighter and doesn’t rust. Aluminum does corrode though, especially if exposed to seawater.
Is anodizing a good finish?
Anodizing is a kind of surface oxidation that can produce some very attractive finishes. However, it’s not usually practical for larger fabrications. If taking the coating approach, don’t forget that any damage needs immediate attention. Leave some aluminum exposed and you risk corrosion getting a toehold.
