The center is copper, inside the really older microwave magnetron the segments were brazed in with gold.

I've only ever come across one with the gold brazing and it is not to likely that I will ever find waveguides from high tech equipment in farming country.

That "scuffing" is where I filed it to confirm it was copper before I continued dismantling it.
I do a lot of checking since I have been coming across a lot of motor windings made with aluminum wire instead of copper. It really sucks to tear apart a motor only to find aluminum wire.
Live and learn.
