Kanthal is the trademark for a family of iron-chromium-aluminium (FeCrAl) alloys used in a wide range of resistance and high-temperature applications. Kanthal FeCrAl alloys consist of mainly iron, chromium (20–30%) and aluminium (4–7.5 %). The first Kanthal FeCrAl alloy was developed by Hans von Kantzow in Hallstahammar, Sweden. Its name is derived from Kantzow and Hallstahammar. The alloys are known for their ability to withstand high temperatures and having intermediate electric resistance. As such, it is frequently used in heating elements. The trademark Kanthal is owned by Sandvik Intellectual Property.
Due to the properties of Kanthal wire it was soon introduced into electronic cigarettes. It has given rise to the ability to make coils that produce enormous amounts of heat without failing as would happen if using conventional wire.
