  • A BRIDGE TOO FAR: MEASURING ELECTRICAL CONDUCTIVITY

    SI units, IACS conductivity is 58.2 MS/m. With a specific conductivity defined as , it . would seem to imply that this is a maximum value of conductivity. However, with modern processing some forms of copper can now exceed IACS, with reported values as high as 103% IACS. Commercially pure silver has a conductivity of about 108% IACS.
