magnetron from microwaves

The pink ceramic contains BeO which is not worth the penny's you collect in breaking it.

Thanks Eric I'll add to what I posted over at GRF here, I chuck the copper part of the magnetron into the lathe then use the sawsall to cut the metal ends off with out harming the ceramic. The solder does not contain any silver, some of the very old magnetron's did have gold brazing but i have only found one in the many years i have been stripping these things apart.

In the second pic, it looks like copper, and the above picture looks like cast iron or something?

Is that what they look like, after you remove the copper?

They are Cu. The dark stuff on the Is copper oxide this happens when they get hot. that's why they have the cooling fins.
