Aluminium does corrode, but after this does not corrode at all because aluminum is a reactive metal. Normally, aluminum is protected by a thin layer of oxide making it inert (unreactive).
However, you can remove the layer of aluminum oxide by submerging the aluminum metal in Mercury(II) chloride. Upon treatment, aluminum is stripped of its oxide quickly and becomes covered by a thin layer of an amalgam (a substance formed by the reaction of mercury with another metal). Once amalgamated, aluminum can undergo a variety of reactions. (eg: it will dissolve in water, which can be dangerous, as hydrogen gas and heat are generated).

Do coins corrode?
Of course coins corrode. Over time coins corrode. They corrode faster in tap water. Bleach also corrodes coins. If you have time, try some experiments and see what substances corrode coins.
Why do copper pipes carry hot water corrode faster than pipes that carry cold water?
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
Why is that a piece of aluminium foil exposed to moist air does not corrode even though aluminium is more reactive than iron which easily rust?
Aluminium reacts very rapidly with the oxygen in the air to form a thin film of aluminium oxide covering the entire surface of the aluminium in the foil. This surface is invisible to the eye. Aluminium oxide is very resistant to chemical processes, like corrosion. It protects the aluminium underneath very well, so aluminium does not corrode in moist environments. If the aluminium is scratched, an new aluminium oxide film forms immediately, protecting the scratched part. Iron does not form a protective skin, because iron oxide has different chemical properties to aluminium oxide and is not able to protect the iron.
What are the effects of seawater as a boiler feedwater?
Fresh water: Can start the oxidation of iron or steel, and the pitting occurs because a small electrochemical form between the rust-metal interface.Sea water: They can corrode the boiler five time faster than freshwater.Distilled water: Can cause the boiler corrode also because deionized water is amazingly corrosive.
Why does zinc reacts faster then aluminium?
it is a metal
How many days does aluminium take to get corrode in water?
Al is resistant to water-corrosion and will only corrode in acid-based conditions (pH<7).
What type of water corrodes water faster?
I do not think that water can corrode, can it?
Does a penny corrode faster in water or orange juice?
orange juise
Do coins corrode?

Does stainless steel corrode quicker than aluminium?
No
Does a nickel corrode faster in salt water than in tap water?
All metals will corrode faster in salt water than in tap water. Corrosion involves the movement of ions and electrons. Having extra ions in the water (salty water has sodium and chlorine ions) speeds this up.
Why do copper pipes carry hot water corrode faster than pipes that carry cold water?
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
Why buy a car made from aluminum?
aluminium does not corrode as easily
Will sprite corrode faster than coke?
yes it will i did an experiment and sprite does corrode faster and better than coke.
Does metal corrode faster than plastic?
Good question! YES indeed metal does corrode faster than plastic!
Does iron rust faster in vinegar saltwater or freshwater?
Zinc will corrode in vinegar faster than salt water
What is is the chemical coating which stops aliminum form corroding?
Aluminium has a natural coating of Aluminium oxide that prevents it from oxidizing (corroding). This layer forms as soon as the Aluminium is made and is impervious to oxygen and water and prevents further oxididation. Some acids and bases can dissolve this layer and then the Aluminum will corrode.
