Hi Ed, Gary,

Funny Gary that you joked about Aluminum in the UK as opposed to the US. 
You might be surprised to find the vast numbers of aluminum alloys out 
there on the market, and their conductivity (the inverse of resistivity) 
vary's greatly! Today I was adding the ability of Javatc to include 
copper or aluminum wire by simply changing the resistivity value (simply 
a check box in Javatc for Aluminum or Copper). As magnet wire is 
annealed copper, it's resistivity is well known. So, I started looking 
for aluminum magnet wire to insert a correct resistivity value and 
stumbled across an interesting table of data.

Thought I'd share since were on the subject:

The conductivity for various aluminum allows is amazing!

Take care,
Bart

	Link didn't work but not surprised at the variability.  The stuff I used was "ground wire" and turns out to be 0.125" dia so bigger than #10.  Wonder what it's composition might be?  Cheapest available I suspect.  It's relatively hard so that probably means alloy although perhaps relatively pure aluminum also can be had in different hardnesses.
