Some transformers are worth stripping while others are best left for the CBM bucket. Large transformers like those from microwaves or UPSes are worth breaking down ONLY if the windings are indeed copper and not copper plated aluminum. easiest way to tell would be to clip the end of one of the terminal wires on the transformer and look at it to see if the underlying metal is metallic red or silver in color. If you see silver, stop right there and toss the transformer into your CBM bucket. If it's metallic red, then go ahead and break the transformer open. If you need additional input on transformers and motors to break open, search youtube for videos by Mike the Scrapper, Moose Scrapper, and Jack the Scrapper.
