Electrical Conductivity

Physical Properties

Определение

A measure of how well a material conducts electric current, typically expressed as a percentage of the International Annealed Copper Standard (IACS) or in S/m. Higher conductivity means lower electrical resistance.

Подробное объяснение

Silver has the highest electrical conductivity of all metals (106% IACS), followed closely by copper (100% IACS) and gold (70% IACS). Aluminum, at about 61% IACS, is used in power transmission lines due to its lower density and cost. Alloying elements such as iron, manganese, and zinc significantly reduce the conductivity of copper and aluminum.
