I posted this elsewhere and got no response, so thought i'd try here which
seems a more appropriate group, any reccomendations for posting would also
Whilst looking into OFC speaker cables (and finding out that they are really
a waste of money) i came across sa few places that claimed OFC copper was
less prone to oxidation due to it's oxygen content being practically zero.
However i think this is absolute rubbish as the oxidisation is caused by air
and water in contact with the surface and has nothing to do with the
internal content of oxygen in the actual metal.
Incidentally i believe the real reason for using OFC free is it's slightly
lower resistance, but thi s is so small it would only be noticeable over
very long distances (over 40M) or where the equivalent copper cable was to
the required current. Also note that as speaker wire is normally sheathed
and soldered to connectors (or should be) oxidisation is no concern really
But i'm not really interested in discussing this, i want to know, is there
any truth in the comments that OFC doesn't oxidise as bad as normal copper,
i can't find anything to substantiate this claim (nor anything disprove it
except what i have been taught and learnt from books). If anyone has proof
it would appreciated as long as it's from a trustworthy source and not Joe
