RE: Aluminum magnet wire?

Hi Aric, All:

Many years back, aluminum was used for the electrical 
wiring in buildings, but this practice was stopped because
aluminum's resistance to electrical flow increases dramatically
as it ages and oxidizes. I would imagine the same sort of thing
 would happen with the magnet wire. also, aluminum, can, 
under the right circumstances, react violently with Ozone. 
I'd stick with the copper.
