24AWG 35AWG IEC 60584 Class 1 K Type Thermocouple Wire Chromel Alumel NiCr-NiAl Bare Wire

24AWG 35AWG K Type Thermocouple Wire NiCr-NiAl KP/ KN IEC 60584 Class 1 / Class 2

K Type Thermocouple Wire is a high-performance thermoelectric alloy material widely used for precise temperature sensing and measurement in industrial applications. It is composed of a Nickel-Chromium (NiCr) positive conductor and a Nickel-Aluminum (NiAl) negative conductor, providing stable thermoelectric output and reliable temperature measurement performance.

Known for its excellent oxidation resistance, good high-temperature stability, and consistent thermoelectric characteristics, Type K thermocouple wire is an ideal choice for manufacturing temperature sensors, thermocouple probes, and industrial temperature monitoring systems.

Our K Type Thermocouple Wire is manufactured under strict quality control to ensure consistent chemical composition, uniform wire diameter, and reliable thermoelectric EMF performance. We offer various wire sizes, surface finishes, and accuracy classes to meet diverse customer requirements.
