The Type K thermocouple wire is composed of two distinct alloys - the positive leg (KP leg) made of Chromel (Ni90Cr10) and the negative leg (KN leg) made of Alumel (NiAlCo/NiSi3). This combination creates a reliable temperature measurement solution with excellent performance characteristics.
Our thermocouple wires are manufactured to meet multiple international standards including IEC 584-1/2/3, ANSI MC 96.1, ASTM E230, DIN EN 60584-1/2, and JIS C1602-C 1610. This ensures compatibility and reliability across different industrial applications worldwide.
The Type K thermocouple is particularly valued for its wide temperature range, with maximum continuous operation at approximately 1,100°C. Its relative radiation hardness makes it suitable for nuclear applications, while its general reliability and cost-effectiveness have made it the most commonly used thermocouple type.
We offer this thermocouple wire in various forms including solid bare wire (from 0.1mm to 8.0mm diameter) and can provide oxidized versions for sizes between 1.2mm to 8mm. Stranded wire configurations are also available upon request for specific application requirements.
For applications requiring precise temperature measurement in challenging environments, our Type K thermocouple wire provides consistent performance and durability. The nickel-chromium/nickel-alumel combination offers excellent resistance to oxidation and maintains stable thermoelectric properties over extended periods.
Our manufacturing process ensures tight quality control, resulting in thermocouple wires with uniform composition and consistent thermoelectric properties. This attention to detail makes our products suitable for critical applications where measurement accuracy is paramount.
Whether you need standard sizes or custom specifications, we can provide thermocouple wire solutions tailored to your specific requirements. Our expertise in alloy manufacturing allows us to meet the diverse needs of industries ranging from power generation to chemical processing.
