Surface resistivity of electroless nickel plating

I was wondering what the typical surface resistivity of electroless nickel plating is? More specifically, the value correlating to ASTM D257...thanks

I have read in a Circuitree Magazine Article(6/1/01) that the resistivity of Electroless Nickel Phosphorous Plate is 55-90 micro-ohms-cm. What is interesting is that the resistivity for nickel is 7.4. Can anyone explain why? Is it the phosphorous content?

Hi Rob. Surely. Even very small amounts of contaminants or alloying materials radically reduce conductivity.
