Is iron the ONLY ferrous pure metal, while every other ferrous metal is an alloy?

Question

I’m having a hard time wrapping my head around classifying metals. So far, I’ve seen two divisions:

1. Pure metals and Alloys

2. Ferrous and Non-ferrous

But I haven’t exactly seen a source that takes both classification divisions into account. Sources keep saying ferrous metals contain iron, so is iron the only pure metal that’s ferrous? Is iron even a ferrous metal? What about the other magnetic metals like nickel and cobalt?

Answer 1

Ferrous means “contains iron.” So yeah, if it’s ferrous and pure it can only be iron.

If you’re asking about “ferromagnetic,” which means that a material reacts to magnets like iron does (attracted to a magnet, can amplify a magnetic field, can turn into a permanent magnet), then there are other metals that have this property including cobalt and nickel.
