Yes, Copper wire is not suitable in Potentiometer.
[There is a used of Manganin wire in potentiometer]
Reason/Explanation :-
While doing experiment we observe that the potentiometer having high temperature coefficient of resistance.
It has also small resisitivity.
On the other hand copper (wire) is a well conductor of electricity as well as low resistance capability .
Hence even a slighter change in temperature can cause huge change in it's resistance, So, In result the experiment will be affected.
Hope it Helps :-)
