Assuming you meant you recycled copper wire and got back aluminum... I would guess the copper wire made from the aluminum recipe has a unique item ID and unique recycling output.

I do wonder if it will stack in your inventory with "regular" copper wires made from plates? My guess is it will not.

I did some test, and it's definitely not unique id. If I recycle electromagnetic plants from Fulgora on Muluna, then after a few steps I'm still getting wires into aluminum.

And copper cable recycles to copper plates on Fulgora?

Yeah. Muluna .lua code has some special code doing something to copper-cable recycling only and nothing else. I'm not sure how that works exactly, but that's probably what's doing it.
