I’ve learned that copper wire is not generally used in a potentiometer. Is there any specific reason for this?
Why is copper wire not commonly used in potentiometers?

Generally the big problems you would face in using copper are: (1) low resistivity; (2) work-hardening; and (3) the formation of copper oxide. All of these could be overcome, but it's so much easier to just use resistance wire.
