Well, there's typically two types of materials-Those with positive temperature coefficient and those with negative temperature coefficient.

Positive temperature coefficient are those whose resistance increases as temperature increases.

Negative temperature cofficient are those whose resistance decrease when the temperature increase.

There are however some alloys such as Manganin& Constantan whose resistance is not affected by temperature
