Information on material electrical resistivity (or conductivity) and magnetic properties (eg. permeability) is vitally important when setting up eddy current probes for inspections, and when mathematically simulating these electromagnetic signals. A valid model must make use of material properties from reliably documented measurements.
Comprehensive tables of electrical conductivities of various commonly tested metals at typical ambient temperatures (~ room temperature) are listed at the following sites:
