Pure copper has 100% IACS conductivity. Copper allloys have conductivity between 99 and 86% IACS.
Rhodium which is much harder than platinum and palladium, typically 800-1000 HV, and has exceptionally high corrosion resistance. It has
electrical conductivity of 38% IACS. This makes it the most electrically conductive of the platinum group metals.
Some idiot reads the last sentence above which is made in the context of platinum group of metals, and later thinks Rhodium is one of the best conductors of electricity amongst all conducting metals.. .
