Quoting Bart, "If I had to pay their prices in a US economy and cost of

aluminum primaries acceptable? Why are they not widely  used?

Hi Clive,
 
Aluminum will have higher resistive losses than copper for the same size  
conductor.
 
Rolls of aluminum tubing are not readily available in most places, you  will 
probably have to use wire.
 
Aluminum wire with the same power handling capacity as copper tubing is  
going to be larger and more difficult to work. The 1/4" copper tubing  will 
require #2 Solid Aluminum wire or larger.
 
On the other hand, what is available to you and what you can afford is,  
IMHO, far superior to what you can't.
 
Hope this helps,
 
Matt D.
