It depends on the Copper itself. If you are referring to PCB Copper, then be
aware that its resistivity is much higher then really pure copper.

Betreff: [SI-LIST] Resistivity of copper
I would like to know the resistivity of copper at 540 degrees C, assuming it is
1.72 * 10^-8 Ohm*m²/m at 20 degrees C. The temp coefficient of resistivity is
.00393 at 20 degrees C but using this I get a result of around 5.31 at 540
degrees. But a problem I am solving says it is closer to 4.30. I am having
trouble resolving the difference.
Can anyone confirm the (approx.) 4.3 number for me?
Thanks for any help.
Doug Brooks
