Product Description
- Ni90Cr10 Heating Resistance Wire
Ni90Cr10 is kind of nickel-chromium alloy products, it is suitable for temperature applications up to 1250°C. Chromium content provides very good life time, it is usually used as a vape heating element.
Ni90Cr10 is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability. NiCr Alloy is a good material for heating industry.
- Thermocouple Element
Ni90Cr10 resistance wire is employed as the sensitive part of the thermocouple, forming a thermocouple with another metal (such as platinum-rhodium alloy). When the temperature changes, the thermoelectric potential difference between the different metals alters, generating a voltage signal that reflects the temperature variation.
- High-Temperature Measurement
The application of Ni90Cr10 resistance wire in thermocouple protection tubes enables temperature measurement in high-temperature environments. Due to its high-temperature resistance and stable resistance-temperature characteristics, thermocouples can accurately measure temperatures at high levels, typically ranging from hundreds to thousands of degrees Celsius.
- Chemical Inertness
Ni90Cr10 resistance wire exhibits good chemical inertness, able to withstand corrosion and erosion from many chemical environments, thus protecting the thermocouple element from damage and extending its service life.
- Industrial Applications
Ni90Cr10 resistance wire thermocouple protection tubes are widely used in high-temperature measurement and control processes in industrial production, such as steelmaking, chemical production, and high-temperature furnace refining.
