Heating conductor wire (also known as heating wire or resistance wire) is an electrically conductive wire made from special alloys, specifically designed for generating heat. Due to its electrical resistance, it converts electric current into thermal energy—a principle used across a wide range of industrial, commercial, and household applications.
Heating conductor wire operates based on Joule’s law: As electric current flows through the wire, its specific electrical resistance generates heat. The physical properties of the alloy—such as temperature coefficient, resistance stability, thermal conductivity, and oxidation behavior—are critical to its performance.
Heating conductor wire is a versatile component used across many industries:
- Household appliances: kettles, toasters, hair dryers, heating plates
- Industry: tubular heating elements, extruders, heating tapes, furnaces
- Automotive: seat heating, battery thermal management, exhaust gas heating
- Medical & laboratory: heating mantles, incubators, thermoelectric devices
- Measurement technology: test benches, temperature compensation systems
Berkenhoff has developed special resistance alloys under the bercotherm® brand that are optimized for such applications. These alloys are characterized by their high resistance and thermal efficiency, which makes them ideal for use in heat conversion processes.
