WebJun 26, 2024 · This table presents the electrical resistivity and electrical conductivity of several materials. Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity, the more readily the material permits the flow of electric charge. WebAdvancements in copper refining allow even higher conductivity of minimum 101% IACS routinely obtained with C110 commercial copper. The fundamental measurement of electrical resistivity in μΩcm, as described in an ASTM standard ( ASTM 1992 b), is divided by 172.4 to obtain the corresponding IACS number.
