Talk:Oxygen-free copper

From Wikipedia, the free encyclopedia

[edit] Removed comments from article

I removed two comments from the article left by Bobahlouie (talk · contribs):

(Actually, I believe this is confusing the difference between oxygen-free and low-impurity copper. Removing oxygen does not necessarily improve conductivity. In fact, for standard ETP electrical copper, oxygen is added to oxidize impurities that would degrade conductivity and therefore improve conductivity. So, when oxygen is removed, if excellent conductivity is still desired - impurities must also be removed. In fact, most oxygen free copper is used not for conductivity improvement (or even audio cables), but for resistance to hydrogen embrittlement in high-temp applications such as welding. Removing oxygen can also change/degrade mechanical properties, such as hardness, etc. See http://www.copper.org/innovations/1997/Dec1997/wiremetallurgy.html)

The difference in resistance is quite small (about 20%) [...] (This statement is not correct - ) By definition all copper for commercial and residential wiring is known as C110. C110 is what you'll find used in Romex at home depot. C110 is also by far the most widely used in any electronic wiring application. C110, C101 and C102 have conductivity within 1% or less, not 20%. See http://www.copper.org/innovations/1997/Dec1997/wiremetallurgy.html and http://www.copper.org/resources/properties/microstructure/coppers.html).

It would be great if that could be seamlessly integrated into the article. You are welcome to remove any unreferenced information, or information supported by poor sources. For more information, you can see the verifiability policy. -- intgr 08:40, 25 April 2007 (UTC)

[edit] Thanks for cleaning up the reference!

I'm new and although I plowed through the tutorial and help stuff, I guess I got a bit bogged down (wow this is complicated!) and blundered in to it all. I'll try to update this in the future with more relevant and accurate facts and applications about OFC. :-)
