All metals corrode to a greater or lesser extent. Some corrode less than others - Gold, Platinum and Mercury to name but three. There are many more mostly in the transition section of the periodic table.

Hi Manu...Hope this is what you were asking for...
Stainless steel pretty much doesn't rust at all, but unfortunately it does have other elements usually chronium and nickel. Aluminum is fairly resistant but here again forms a thin oxide layer quickly.Platinum and gold is pretty much resistant to corrosion also.And copper.
Cast iron is also classified in this catagory also because of the free graphite content of this metal (3-4%) by weight or about 10% by volume, an insoluble graphitic layer of corrosion products is left behind in the process of the corrosion. Hope this has helped...Have a good day!

I'd ignore the smart *** above although he has a good point.
I take it you mean corrosion due only to the atmosphere. Gold silver or copper are some of the best metals at resisting corrosion. Silver and copper will form a fine layer of oxide\tarnish which protects them from furthur corrosion

Mercury, Gold, Platinum there also is silver also I'm not sure if Sodium corrodes or not

All metals corrode to some degree.
Gold, Titanium and Aluminium are probably the best examples as these produce an oxide which prevents them from corroding further

If you want metals that hardly oxidise in normal atmosphere: Gold, Platinum, Rhodium, Iridium (as inert as gold).
There are metals that have good resistance to normal corrosion in air-water mixture but are not as inert as above: copper (the green oxides and carbonates offers some protection, used in roofing), zinc, aluminium, tin, nickel, chromium (plating).

How do you define corrosion?
If you define it as oxidation or subject to action by strong acids, *any* metal will corrode, including gold and platininum.
Wiki "aqua regia".

Aluminium, Gold and Platinum are those which do not corrode.
Gold and Pt are noble metals
Aluminium is a self protecting metal--is protected due to thin oxide layer formation
