Hi Vicka! Here are the numbers my references have:
For Acid copper 1.70-1.82 microohm-cm
For Pyrophosphate copper 1.73-1.75 microohm-cm
The specific bath chemistry and additives seem to push the resistivity
values around.
Good Luck.

Does anyone have accurate information of the resistivity of plated
copper as compared to copper foil?
I have done some research and found that there are a lot of conflicting
statements out there. I have seen it published anywhere from plated
copper being 4.8 to 6 uohm cm.
