Electrical Conductivity of Common Zinc Alloys

Zinc alloys typically exhibit good electrical conductivity, although it may not be as high as that of some other metals like copper or aluminum. The electrical conductivity of zinc alloys depends on their composition and specific alloying elements.

The following table provides a curated list of electrical conductivity values for common zinc 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)
