[TCML] primary material? (interview)

As primary resistance and Q are important, we usually choose copper as the first choice to optimize these things. Exactly how much performance would suffer if aluminum were substituted, I don't think, has ever been experimentally tested. It would no doubt depend on many things, especially the primary inductance (losses will be higher in a low inductance primary).
However, there are better reasons to stick with copper. The ability to solder and splice copper, and to use a tap clamp without worrying about the oxide layer are important. The cost of 1/4" copper tubing, relative to the total cost of a coil, isn't huge in my opinion.
