Aluminum does not rust. Alumininum can also be anodized to keep it from corroding when salt and other contaminats get on it.
Copper doesn't rust
If they are an alloy, they will eventually rust.
Under most conditions aluminum will not rust in water. However, if the aluminum is alloyed with another metal, oxidation (rusting) could take place.
Aluminum corrodes rapidly on its exposed surface, but unlike the rust on iron which catalyzes more corrosion, this corrosion layer is protective and once it is thick enough corrosion stops. After that aluminum can last almost forever, unless the layer is damaged.
How long will it t take a quarter to rust in fresh water
As long as you take proper care of them they should last you quite some time. Since aluminum is lightweight and can typically withstand different weather conditions, you should be just fine.
a long time
It depends on the quality of the nail. If it is painted it Amy take long to rust. In general it may take a month or so for the nail to rust.
