Nickel Grade Nichrome Chromel Alloy Wire Ni35cr20 Wire Used For Thermocouple

  • Ni35Cr20 Heating Resistance Wire

Ni35Cr20 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.

A thermocouple is a sensor used to measure temperature, based on the thermoelectric effect between two different metals or alloys. Ni35Cr20 resistance wire is commonly used as one of the metals, paired with another metal such as copper or platinum.

  • Temperature Measurement

Ni35Cr20 resistance wire is commonly used as heating elements in electric furnaces. Its high temperature stability and low resistance temperature coefficient enable it to provide stable heating effect in high temperature environments, thus meeting the heating requirements of different materials.

  • Electric Water Heater

The primary role of Ni35Cr20 resistance wire in a thermocouple is as a temperature sensing element. When the junctions of the thermocouple are at different temperatures, a thermoelectric potential is generated, which can be measured to determine the temperature of the environment. The stability and reliability of Ni35Cr20 resistance wire ensure accurate temperature measurement results.

  • Industrial Applications

Ni35Cr20 resistance wire thermocouples are widely used in temperature monitoring and control in industrial settings. They can be applied in various scenarios such as furnace temperature monitoring, furnace temperature control, temperature measurement in chemical processes, and more.

  • Laboratory and Research

In laboratory and research settings, Ni35Cr20 resistance wire thermocouples are also common tools for temperature measurement. They are used in laboratory instruments, scientific research, and various testing and analysis applications.
