Electrical conductivity of WC

[shantanu]

Dear all,

We all know that WC coatings applied using HVOF are electrically conductive

but is there a measure of the extent of conductivity or resistivity in unit terms like w/m/k or

How do we a certain whether a certain amount of current shall pass through the coatings and the coatings shall be conductive?

Await your reply

Regards

Shantanu

Dear Shantanu,
Pl let me know the exact application of WC for electrical conductivity?
Regards.

Dear Shantanu,

I am wondering also for the electrical conductivity of WC.
So I have searched the resistivity.
The electrical resistivity of WC is 0.0000530 - 0.0000800 ohm-cm.
Tungsten is 0.00000565 ohm-cm.
However sintered 6%Co+WC has 0.00000200 ohm-cm.
If you want to review the data, refer the following site.
