Description

1.29mm and 1.02mm Diameter K Type Thermocouple Wire Chromel Alumel Thermocouple Bare Wire with Oxidation Resistance

Product Overview

Heavy Gauge K Type Thermocouple Wire is specifically designed for demanding industrial temperature measurement applications that require excellent mechanical strength, high-temperature durability, and reliable thermoelectric performance.

Manufactured from Nickel-Chromium (KP/Chromel) and Nickel-Aluminum (KN/Alumel) alloys, our K Type Thermocouple Wire offers excellent oxidation resistance, stable thermoelectric output, and outstanding performance in high-temperature environments.

Compared with fine diameter thermocouple wires, heavy gauge wires provide greater mechanical strength, improved resistance to wire breakage, and longer service life under suitable operating conditions. They are particularly suitable for industrial furnaces, heat treatment equipment, and heavy-duty temperature sensing applications.

Our K Type Thermocouple Wires are produced with carefully controlled chemical composition, uniform wire diameter, and consistent thermoelectric properties to meet the requirements of industrial thermocouple manufacturers worldwide.
