There isn't one.
The name 'Ferrous' means 'of iron' from Latin, and iron DOES RUST.
All ferrous metal rust to a greater or lesser degree. Certain elements are added to iron to inhibit this, these metals are called alloys. One such example is stainless steel
There is only one ferrous metal-iron- but there are many ferrous alloys. Iron and the iron in most of the alloys will oxidize quickly-that is, rust.
Ferrous rust's and non ferrous doesn't. :))
Rust
Yes
to make ferrous metal all you have to do is mix iron with a certain type of metal to make a non ferrous metal well you don't have to any metal that doesn't have iron in it is a non ferrous metal
Mostly they rust easily (oxidise) unless protected eg. with oil
It wont because it is non ferrous metal of course

A 25 cent coin (quarter will not rust- they are no made of ferrous metal. They may tarnish- usually from exposure to air and sulfur.
