Search for a material with electrical resistance and high hardness
(OP)
Please someone could help me search for a material with good properties of wear resistant or high hardness and simultaneously with electrical resistance features. This material is to be used as a tool disc to block and guide a fin strip plate and push it against tube where is to be welded with high frequency welding process, in that matter a reason to avoid electric current passing through the tool because it erodes the material regarding the effects of electrical fatigue.
The prevision of service conditions are:
Temperature = 40ºC up to 100ºC
Pressure = 40 Barg
I appreciate all your help on this. Thanks.

I have seen machines for brazing and welding where they use a standard machining insert. Easy to buy, relatively inexpensive and easy to replace.

You haven't mentioned the configuration of your guides like vertical rods, parallel blades, doctor blades, rollers, etc.
If possible comeback with that information.
Here is the some general information on Sapphires.
