Substitution will indeed continue while this discrepancy persists. There are not so many applications where density is a more important factor than cost or weight. Their is a tradition and cultural bias to overcome however and this could take time.<br /><br />One other factor in the decision is the recent but rapidly growing phenomenon of copper theft. In many instances this may make copper a poor choice for infrastructure. Security hasn't been a consideration in the past and will certainly increase the cost. It is an indication that copper has become too expensive for its most basic purpose. It may have to choose between being an industrial metal or a financial metal, to be hoarded like gold, rather than consumed.<br /><br /><br />Dexter Blandnoreply@blogger.comtag:blogger.com,1999:blog-49429371230804057.post-58054143809111793432012-08-27T07:02:08.978-04:002012-08-27T07:02:08.978-04:00Check out the following interview: http://www.mine...Check out the following interview: http://www.mineweb.com/mineweb/view/mineweb/en/page96990?oid=157374&sn=2010+Detail&pid=92730<br /><br />GEOFF CANDY: Looking at the substitution issue and its one you mentioned earlier, how significant is that going to be going forward, because surely it would at least theoretically put a cap on prices if you see a significant amount of substitution?<br /><br />SIMON HUNT: I don't know about a cap on prices because as I said earlier it comes back to the money game. But substitution going forward is going to probably be at a rate faster than we've actually seen since 2005, and that in itself has been pretty big. I would say averaging close to half a million tons a year. We've got new technologies coming in, high temperature super conductors, carbon nanotubes, we're seeing aluminium now being used in aircon compressors which has never happened before, and currently from what I hear probably around 20% of the compressor market in China is now using aluminium wiring. So everybody, every end consumer is doing their utmost to limit the amount of copper that they use either through improved designs or by outright substitution or by technology. That is because of the absolute price and the volatility of price - the two together.<br />Anonymousnoreply@blogger.com
