Jon,
     Aluminum should be fine, as long as it is thick enough to not overheat 
and melt.  It is a better conductor than brass but I believe this may not be 
true at radio frequencies.  Anyway, there is no way a thin aluminum oxide 
layer will insulate against TC voltages, I use it for some of my connectors, 
as it is cheap and easy to machine.  Best of luck.
Scott Bogard.
