Electrical Conductivity of Common Aluminum Alloys
Aluminum alloys are widely used in electrical applications due to their high electrical conductivity, low weight, and good corrosion resistance. The electrical conductivity of aluminum alloys is typically lower than that of pure aluminum, but it can be improved by alloying with certain elements, such as magnesium, silicon, and copper.
The following tables provide a list of electrical conductivity values for common aluminum alloys in both International Annealed Copper Standard (%IACS) and Siemens per meter (S/m) units.
Unless stated otherwise, all values are taken at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
