High-temperature furnace resistance wire is a type of wire specifically designed to withstand extreme heat conditions typically found in furnaces, kilns, ovens, and other high-temperature industrial applications. These wires are typically made from alloys that can maintain their mechanical and electrical properties at elevated temperatures.
The most common alloy used for high-temperature furnace resistance wire is called Nichrome. Nichrome is an alloy of nickel, chromium, and sometimes other elements such as iron. It has high electrical resistance and excellent oxidation resistance at high temperatures, making it ideal for heating elements in furnaces and other high-temperature environments.
Other alloys used for high-temperature resistance wire include Kanthal (an iron-chromium-aluminum alloy) and FeCrAl (iron-chromium-aluminum), which offer similar properties to Nichrome.
