Aluminum and Copper conductivities compared

 

TABLE OF IACS (International Annealed Copper Standard) CONDUCTIVITIES FOR ALUMINUM & COPPER ALLOYS

100% IACS is equivalent to a conductivity of 58.108 megasiemens per meter (MS/m) at 20°C or a resistivity of 1/58.108 ohm per meter for a wire one square millimeter in cross section. IACS by volume are a measure of current per pound compared to copper.
IACS % = (172.41/resistivity) where resistivity, ρ,(ro) is in micro-ohms per centimeter.

*Aluminum IACS by weight:
Aluminum equivalent IACS % by weight are shown to demonstrate that aluminum will transmit 1-1/2 times (lugs) to 2 times (aluminum cables) the current that the same weight of copper would.
As most heat dissipation for UL conductors, cables and connectors is by convection, larger aluminum cables and lugs are better able to dissipate heat since the surface area of the conductor or connector lug is the key to passing heat into air.
