Cr20Ni30 Heating Resistance Wire is an austenitic nickel-chromium alloy suitable for temperature applications up to 1100°C. This alloy features high resistivity, excellent oxidation resistance, good post-use ductility, and superior weldability. Ni35Cr20 is widely used in electric heating elements for domestic appliances.
Applications
  • Resistor Adjusters: Cr20Ni30 resistance wire regulates resistance values in circuits to control current or voltage magnitude, commonly used in dimmers and speed controllers.
  • Current Limiters: Serves as a key component to generate appropriate resistance and protect circuits from overload damage.
  • Resistor Networks: Used in constructing resistor networks for signal conditioning, filtering, and impedance matching applications.
  • Sensors and Measurement Equipment: Functions as a critical component in resistance-based sensors for measuring temperature, pressure, and humidity with high accuracy and reliability.
