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.

∙ 15y agoAluminium corrodes faster as it has a higher negative electrode potential than iron, however this is beneficial as the Al2O3 oxide layer forms a protective barrier to inner metal degradation through its self passivating properties. Ductile / Gray iron corrodes at a slower rate, however it is more detrimental to the properties of the metal as there is no protective layer formed and the rust eats further into the metal.

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.
How would you separate copper strands and iron filings?
I would separate copper strands and iron filings by using a magnet. The iron is magnetic, but the copper is not, so the magnet picks up the iron, but leaves the copper behind.
Does water affect pennies?
As pennies are not made of iron, they cannot rust under any circumstances.However they can corrode. The copper shell will produce a green corrosion product, the zinc core can corrode completely away as a transparent water soluble corrosion product. This corrosion will be very slow in plain water (much slower than iron rusts in water) but will be much faster if an acid is added to the water.
What will happen if copper metal is added to iron sulfate solution?
nothing will happen as i have done this experiment. I think it is because iron is more reactive than copper, so the copper can't take away the sulphate. but if you added the iron to a copper sulphate solution the product would be iron sulphate this reaction is called displacment.

How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
If steel and copper were in contact in an electrolyte which would corrode?
Steel will corrode as the iron in it is more reactive than copper.
Can copper pennies rust?
NO!!! Because they are made of copper NOT iron.
Why are copper and iron not used to make earrings?
Because they corrode and stain on skin contact.
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.
What makes copper not rust?
"Rust" is the result of a reaction between iron and oxygen. Copper has no iron in it, so does not rust. It can corrode, though, and yield a bright whitish-blue material.
Which metals rust faster steel zinc-coated steel iron or copper and why?
I would like to make two things clear. -Copper is metal, so your question is like "What tastes better? Fruit or apple?" - Rusting is restricted to Iron, another metal. The word "Corrosion" is used for all other metals, such as Copper. Corrosion and Rusting are pretty much the same, but they are used in different places. If you wanted to know if Other Metals corrode faster than Copper, the answer would be that it depends on the metal in question. Most metals, like Iron, Aluminum, Zinc,etc , are more reactive than Copper, so they corrode faster. However, some metals, like Mercury, Silver, Platinum, Gold, etc, are less reactive, so they corrode slower than Copper. I hope this answers your question.
Would it matter if you spilt battery acid on a car body which is made of iron?
Yes, it would corrode the iron.
Who is hot first iron or copper?

I would separate copper strands and iron filings by using a magnet. The iron is magnetic, but the copper is not, so the magnet picks up the iron, but leaves the copper behind.
What happen when copper sulphate is stored in iron vessel?
Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.
Which type of nail iron or copper would stick to magnet?
The iron nail would stick to a magnet. Copper is not attracted to magnets.
