Okay ... but we are talking about copper here. What other materials do
isn't relavent.

weakly conducting materials? ... In connection with a prototype design I'm developing for a meteorological measurement device, I'm looking for a readily available material with the following physical properties:...Target resistivity of the material is in the range 10 to 10**4 ohm*meter at temperatures between 0 and 100 C. ... Not subject to significant degradation or aging, even at sustained temperatures near 100 C for days or weeks at a time. ... If anyone either knows offhand of a material matching the above description or can point me to a good tabulation of candidate materials,... (sci.materials)
