The list begins with the more active (anodic) metal and proceeds down the to the least active (cathodic) metal of the galvanic series. A "galvanic series" applies to a particular electrolyte solution, hence for each specific solution which is expected to be encountered for actual use, a different order or series will ensue. In a galvanic couple, the metal higher in the series (or the smaller) represents the anode, and will corrode preferentially in the environment.

∙ 12y agoCorrosion occurs when a metal reacts with a chemical in its environment and disintegrates. It is often, but not always, an electro-chemical process. As a consequence, the rate of corrosion of a metal depends not only on the metal but also on the environment. Iron, for example, will corrode rapidly in sea water, especially if the water happens to be somewhat acid. It will corrode extremely slowly or not at all in orbit around the Earth in the vacuum of space.
Thus the question, what metals corrode the fastest, has different answers depending on the environment in which they are corroding.

∙ 13y agoIt strictly depends on the metal you use.
Iron corrodes faster in Sulfuric Acid.. where as lead corrodes faster in a mixture of sulfuric acid, nitric acid and hydrogen peroxide (mixed in right way)
whereas intert metals like gold or silver, corrodes faster in Aquaregia.. so.. it depends on the metal you use

Why does magnesium corrodes faster than iron?
Believe it or not, aluminum is technically more reactive than iron. However, when aluminum is exposed to air, it almost instantly forms a microscopic layer of aluminum oxide (Al2O3) which protects the rest of the aluminum from any further reaction. Iron doesn't do this, and therefore corrodes unevenly, making it unsuitable for certain applications.
How does cast iron react to salt water?
It corrodes badly.
What is the most common magnetic element that corrodes to form rust?
The most common magnetic element that corrodes to form rust is iron. When aligned, atoms of iron will possess a magnetic field that will lead to interaction with other magnetic, ferrous materials. Iron will oxidize to form rust.
What was the metal that replaced bronze in the making of weapons and tools?
I believe it went into the iron age.
Is a ship corrodes a physical or chemical change?
It is a chemical change, the metals are being converted into oxides - like Iron into Iron Oxide (rust).
Which would corrode first copper or iron?
Aluminum (US spelling) is actually much more reactive than iron, and would corrode faster. In fact, it corrodes so fast that in forms a coating of aluminum oxide on any surface in contact with air. But since the surface is covered, it protects the rest of the metal, and it never corrodes deeper than a fraction of a millimeter. So technically, aluminum corrodes much faster, but much less completely because most of the mass of it is protected by the corroded layer.
Does copper or iron corrode faster and why?
Iron generally corrodes faster because the oxide layer (rust) does not seal the metal's surface from oxygen like the corrosion on copper does.
Why does magnesium corrodes faster than iron?

how quickly does an iron nail rust in saltwater?
The combination of moisture, oxygen and salt, especially sodium chloride, damages metal worse than rust does. This combination corrodes, or eats away at, the metal, weakening it and causing it to fall apart. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity. Bacteria in ocean water also consumes iron and their excretions turn to rust.
What corrodes a penny faster?
acid and coke
Does iron heat faster than glass?
iron travels faster
Why are many things that are made of iron disposable?
because iron corrodes and its cheap
Can copper pennies rust?
NO!!! Because they are made of copper NOT iron.
When Iron corrodes in the presence of air and water to form what?
IRON OXIDE.......AKA RUST!
How does cast iron react to salt water?
It corrodes badly.
What metal corrodes easily to form rusty oxide?
This metal is iron.
What type of water corrodes water faster?
I do not think that water can corrode, can it?
