Cr20ni30 Heating Resistance Wire

Ni30Cr20 is an austenitic nickel-chromium alloy suitable for temperature applications up to 1100°C. This alloy is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability. Ni35Cr20 is used for a wide range of electric heating elements in domestic appliances.

Resistor Adjusters

Cr20Ni30 resistance wire is widely used in resistor adjusters to regulate the resistance value in a circuit, thereby controlling the magnitude of current or voltage. These adjusters are commonly found in various electronic devices and circuits, such as dimmers and speed controllers.

Current Limiters

In certain circuits, it's necessary to limit the magnitude of current to protect other components from overload damage. Cr20Ni30 resistance wire is used as a key component in current limiters, generating appropriate resistance to restrict the flow of current.

Resistor Networks

Cr20Ni30 resistance wire can also be used to construct resistor networks for applications such as signal conditioning, filtering, and impedance matching in circuits. Resistor networks typically consist of multiple resistors, with Cr20Ni30 resistance wire providing the required resistance values.

Sensors and Measurement Equipment

In sensors and measurement equipment, Cr20Ni30 resistance wire is often used as a key component in resistance-based sensors for measuring physical quantities such as temperature, pressure, and humidity. Its stable resistance characteristics and high temperature resistance ensure the accuracy and reliability of the sensors.
