Does every different conducting substance have a unique resistivity?

Please note that resistivity also depends on temperature.In the most general case, the answer is definitely NO; all superconductors have the same resistivity, namely zero.
Other than superconductors, take a look at a table with some typical resistivity values. It would seem quite obvious that for a given temperature:
* Two different substances will, in general, have different resistivities.
* In practice, in some cases the difference in resistivity might be too small to reliably measure.
* It should be possible to find two substances that have the same resistivity at a very specific temperature - since the temperature-dependence will vary from one material to another.
* Likewise, it should be possible to design a mix of two substances, which exactly matches that of another, given, substance.
