I had some thick 'copper' foil given to me that is aluminium with a copper finish. It is useful for wrapping round work in the chuck so as to not mark it.
From here I obviously can't tell if yours might be the same (I am good, but not that good
) but it could be an option perhaps?
Just looked and copper plated steel is a commercial product
