• ... that non-ferrous metals are used because of their desirable properties such as low weight or resistance to corrosion?

• I can hardly believe that there isn't an article covering this subject already. I've asked Materialscientist to comment. Schwede66 05:03, 26 October 2011 (UTC)

  It is great to have this article started, but (i) the history section is possibly covered in numerous other WP articles (haven't checked, just intuition - this might become a problem if someone shouts "its a duplicate topic" when the article is on the main page); building ~1500 bytes of prose not counting the history might be a safeguard for this. (ii) The hook is too general and thus incorrect - most non-ferrous metals are heavier than iron (which is pretty heavy) and not all are resistant to corrosion. (iii) I have some doubts that "all precious metals are non-ferrous" [1]. Such general articles are not easy to compose in a balanced way; it is safer to use fewer generalizations (or cite them well) and more examples. Materialscientist (talk) 06:02, 26 October 2011 (UTC)

Thanks for the input, I've added some info on recycling and changed the hook below to fix the issues. I've looked on the other metal articles and found that this article has some similarities with their Ancient history sections. --Lenticel ^(talk) 00:47, 27 October 2011 (UTC)

• ... that scrap non-ferrous metals come from a variety of sources ranging from industrial scrap and obsolete technology to discarded jewelry and electronics?
  • Looks fine - length, date, policy etc. It is surprising there was no article. I suppose the concept is more metallurgy than physics. Good to go. Aymatth2 (talk) 04:02, 17 November 2011 (UTC)
• this topic has been around a long time (in 2005) see http://en.wikipedia.org/w/index.php?title=Ferrous_and_non-ferrous_metals&oldid=29386262 which was called the same name as this at the time. It ended up as http://en.wikipedia.org/w/index.php?title=Ferrous_and_non-ferrous_metals&oldid=203619682 before a conversion to a redirect to what is now a one line in, the ferrous ion article. So this is a re-creation, but certainly worth having this topic as an article. Graeme Bartlett (talk) 10:25, 17 November 2011 (UTC)
  • I don't see a problem. The old version of the article was at 446 visible characters with little content when merged in April 2008. This one is much more complete at 3720 visible characters. It could be seen as an expand, I suppose. Aymatth2 (talk) 16:46, 17 November 2011 (UTC)
