WebThe IACS is an annealed copper standard held at 20°C with an accepted conductivity value of 58×10⁶ S/m [1.72 µΩ-cm]. Therefore, a reported conductivity of 50% IACS implies that the material has half of the conductivity of an annealed copper standard, or 27.5 x10⁶ S/m [3.45 µΩ-cm]. Silver, copper, and gold are reported as having the ...
