  • Ni70Cr30 Heating Resistance Wire

Ni70Cr30 is an austenitic nickel-chromium alloy suitable for temperature applications up to 1250°C. High chromium content (30% in average) provides very good life time, especially in the furnace applications.

Ni70Cr30 is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability. Alloy is not subject to “green rot” and is particularly well suited for reducing and oxidizing atmospheres.


  • Thermal Protection Systems for Spacecraft

Ni70Cr30 resistance wire is commonly used in the thermal protection systems of spacecraft as heating elements or thermal sensors. During re-entry into the Earth's atmosphere, effective temperature control of the spacecraft is crucial, and Ni70Cr30 resistance wire provides reliable heating or temperature sensing capabilities.

  • Aircraft Engine Components

In aircraft engines, Ni70Cr30 resistance wire can be used as heating elements for combustion chambers, nozzles, and other components. In extreme high-temperature and pressure environments, Ni70Cr30 resistance wire ensures stable heating effects, ensuring the normal operation of the engine.

  • Aircraft Temperature Control Systems

Ni70Cr30 resistance wire can also be utilized in aircraft temperature control systems, such as temperature sensors or heaters, to ensure that various components of the aircraft maintain safe temperatures.

  • Aerospace Electronics

In aerospace electronic devices, Ni70Cr30 resistance wire is often used in circuits and electronic components operating in high-temperature environments, ensuring the stable operation of the equipment.

  • Aerospace Experiments

Ni70Cr30 resistance wire is widely used in aerospace experiments, such as serving as heating elements in experiments simulating spacecraft re-entry into the atmosphere or testing the high-temperature performance of aerospace materials.
