Bifurcated! I love that word!
You can cut the aluminum with an angle grinder (Use a vice, Gloves & goggles!)
The copper can then be easily driven out.
I usually set them across a couple of transformers (for support) and use a hammer and a big punch. Then I blast the copper slug out.
Then it turns into money!
Make sure you do this on a concrete floor and not on your workbench, if you can.

I put the aluminum part in a vice and use a grinder to cut the part holding the copper. Then it pops out easy. Otherwise, I could beat on that copper slug forever and it was so tight, it wouldn't budge.

I put it on its side & put the blade of a cold chisel in between the Ali fins & bash it a couple of times. This warps the Ali a bit, loosening the grip on the Copper slug. Then I use a steel punch & hammer to push out the slug.
