What exactly is a non-ferrous metal? By definition, it pretty much anything which does not contain iron. But that's 2/3 of the periodic table. Without sources, I think the important part of non-ferrous metals are that they are economically important (= sold by the tonne, not by the troy oz), and that they are not iron or steel (not structural materials, can be magnetically separated from ferrous metals as scrap). That should cut it down to copper, aluminium, zinc, perhaps lead, tin, and nickel, and alloys thereof. That's what's on the London Metal Exchange's list of non-ferrous metals.

Not all elements named as non-ferrous metals are metals. Selenium is named as non-ferrous METAL? It is only a half-metalloid such as carbon and phosphorus (graphite could also be named as "non-ferrous metal" by analogy to selenium). Tellurium is a metalloid. (talk) 13:22, 9 November 2013 (UTC)

did not pass DYK[edit]

Quite sad that this did not pass the DYK standards but hey, at least we managed to create a Start article out of it.--Lenticel (talk) 00:29, 2 November 2011 (UTC)

Circular definition[edit]

"non-ferrous metal is any metal that is not ferrous"

OK, I could guess that myself, based on language structure. What then is a ferrous metal? The link ferrous metal provides info on the ferrous ion Fe2+. I'm not sure what ferrous metal really means — I can easily imagine the sets {Fe} and {Fe, Co, Ni} and {Mn, Fe, Co, Ni}, depending on magnetic and/or chemical properties to be associated with "ferrousness".

Unfortunately, this picture circulated. The article has come a long way since then and is improving. (talk) 20:47, 4 June 2013 (UTC)
