Electrical Conductivity of Common Titanium Alloys
The electrical conductivity of titanium alloys is influenced by factors such as alloy composition, processing methods, and temperature. Generally, titanium and its alloys are considered to be poor conductors of electricity.
The following table provides a list of electrical conductivity values for common titanium 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)
