Yes, but not red rust like iron, or bluegreen "rust" like copper. Aluminum oxidizes ("rusts") extremely fast on all surfaces exposed to air, and that oxidation is almost the same color of the aluminum, but just a hair on the pink side for a week or so.
Aluminum's hard oxidation actually protects the aluminum. In fact, if you scratched a spot in the protective oxidation, the scratch would re-oxidize in a matter of seconds.
When you weld aluminum, you must use a process that eliminates the oxidation, otherwise the welding will simply melt the aluminum.
To paint aluminum, you must use a primer that cuts chemically through the oxidation, or it will not stick.
Answer:No. However, it does corrode. Corrosion often results from salts and contaminants which leach into the aluminum (oxide) surface. Anodizing is a way of putting an artificial oxide coating on the aluminum. This coating is then often dyed and sealed to protect it. Protected aluminum is pretty good stuff and doesn't corrode if given a little bit of care. Natural aluminum also develops the same sort of coating (which is clear so it is hard to see), but it is more porous and fragile compared to anodized coatings.A

What makes cans rust?
The inside of a soda can is made of aluminum that is why they do not rust they only rust if the aluminum is all scratched up.
Will a aluminum soccer goal rust?
No, aluminum doesn't rust but it can corrode. If there is a sealant or coating on the aluminum to help protect it, then it will last for a long time.
Will galvanized aluminum rust?
Aluminum is not generally galvanized as the zinc would not be readily sacrificial for aluminum. There are steel products which derive rust resistance from a coating of aluminum and zinc alloy. Properly maintained, they will be rust free for 20 years or longer.
Does aluminum rust in coke or tap water?
aluminum doesnt rust. it oxidises so needs oxygen from any source
Will aluminum foil rust in water?
Rust is Iron oxide, so no.
Will your oxidized aluminum easel rust if left in the rain?
Aluminum does not rust. If it is oxidized, and then it is left out in the rain, it will more than likely corrode.Ê
How long does it take an aluminum fence to rust?
Aluminum does not rust. Alumininum can also be anodized to keep it from corroding when salt and other contaminats get on it.
Does aluminum oxide rust?
Yes. In fact, aluminum oxidizes faster than almost any other metal, which is why aluminum foil will, actually, remove rust: The abrasion removes the coating of aluminum oxide that covers all metallic aluminum exposed to the air, and the exposed aluminum metal wants to be oxidized so badly that it will actually steal oxygen from iron oxide, AKA rust, and reduce it back to iron metal. Which is why aluminum foil will, in fact, remove rust. This reaction, interestingly, is the same one that makes thermite work.
How do you make Aluminum rust?
Aluminium does not rust. Iron is the only metal that rusts.
Which is better against rust galvanized or aluiminum lag bolts?
Aluminum does not rust.
What is aluminum grade 356?
poorly refined aluminum that may or may not rust.
What is the prediction for the rusting of aluminum?
Aluminium does not rust.
