 Primaries would with copper ribbon are uncommon but not unheard-of.  The
 main problem is in finding the copper ribbon.  Be sure that the material
 you saw at your steel shop (?) is in fact copper, and not brass, bronze,
 or brass-plated steel.  If you do in fact have a source for 1.5" wide
 copper ribbon, please share it with the list as there are many others
 that would be interested in this.  But I can't believe that copper
 ribbon can be cheaper than 1/4" copper tubing.
 
 Calculating the inductance of a ribbon primary is no different than if a
 normal wire of the same diameter as the ribbon-thickness was wound in a
 flat spiral.  Wintesla will do a fine job.

I bought some copper for my ground rod system from a local company that 
installs copper roofing.  I called them and asked for about 30 feet of 4.0" 
wide copper - which they cut and rolled up for me.  I don't remember the 
exact cost, but it was not cheap.
