Copper is not used as potentiometer wire because?

The resistivity of copper is low. Due to this, a suitable potential drop across the ends of the potentiometer wire will not occur, so the Copper wire can’t be used as a potentiometer.
Copper has a high temperature coefficient of resistance and a low resistivity, hence we do not use it in a potentiometer.
