Default Copper for Headphone Amp Chassis

I'm about to start my Aikido build and am trying to find a suitable chassis to mount everything into. In my search for aluminum plate, I found a suitable piece od 1mm thick copper plate at work and I'm wondering if copper would be a suitable material for this tube headphone amp or should I stick with aluminum. The copper would look stunning all polished up with the tubes protruding thru the top of the case!! There may be EMI issues with copper in this application though. Can anyone shed some light?
Thanks,
D.W.

Coppers is a better emi shield and a better conductor of heat than aluminium... Polish it up then lacquer otherwise it will tarnish. :-)

1mm is a bit thin though surely?

Actually, It's very heavy at 1mm thick. hard to bend as well. It may be too heavy for a desktop headphone amp. I'm still undecided...

Copper is a great material (as long as you do not mind weight/cost).

I suppose ETP would be OK, 1mm just seems like it would be too prone to warping, because its pretty soft, nothing to do with weight. 1mm makes it pretty difficult to mount anything properly too.
