Bottom is copper, fins are usually aluminum. Somethimes the whole thing is nickel plated too, and almost looks like stainless. I usually separate the copper. Clamp the copper bottom in a vise and bust off the fins. I use an air chisel, but you could also use a hammer chisel or even a large screwdriver. The fins usually come off easy.

Check with your yard and see if they will buy them as Al/Cu radiators. This would save you the trouble of trying to harvest the copper.
