Type K Thermocouple Bare Wire (KP/KN) – 0.5mm Diameter
Product Overview
This Type K thermocouple bare wire from Huona is a precision-grade thermoelectric wire pair consisting of KP (Chromel, positive leg) and KN (Alumel, negative leg), designed for manufacturing custom temperature sensors and probes. Manufactured via vacuum melting, precision drawing, and stress-relief annealing, the wire maintains strict thermoelectric accuracy and mechanical stability, making it ideal for both laboratory and industrial temperature measurement applications.
Core Specifications
- Product Name: Type K Thermocouple Bare Wire (KP/KN Pair)
- Alloy Composition:
- KP (Positive Leg): Chromel (Ni: ~90%, Cr: ~10%)
- KN (Negative Leg): Alumel (Ni: ~95%, Al: ~2%, Mn: ~2%, Si: ~1%)
- Diameter: 0.5mm (customizable: 0.1–3.0mm)
- Tolerance: ±0.01mm
- Form: Spool (standard length: 100m/leg; custom lengths available)
- Thermoelectric Performance:
- Accuracy Class: IEC Class 1 (±1.5°C or ±0.4% of reading, whichever is greater)
- Thermoelectric Power: ~40.5 µV/°C at 100°C
- Operating Temperature Range: -200°C ~ 1260°C (continuous use)
- Standards Compliance: IEC 60584-1, ASTM E230, GB/T 4989, RoHS 2.0
- Manufacturer: Huona (Shanghai) New Material Co., Ltd.
Key Differentiating Advantages
1. Precision Thermoelectric Consistency
Every production batch undergoes rigorous thermoelectric testing to ensure strict compliance with Type K standards. This eliminates measurement drift and ensures accurate, repeatable readings even in high-temperature or long-term use scenarios.
2. Excellent High-Temperature Oxidation Resistance
Chromel and Alumel alloys form stable oxide layers at elevated temperatures, providing superior oxidation resistance compared to other common thermocouple types. This extends service life in oxidizing industrial environments, reducing maintenance and replacement costs.
3. High Mechanical Strength & Flexibility
The wire’s fine-grained microstructure delivers a tensile strength ≥650 MPa and elongation ≥25%, making it suitable for both rigid probe construction and flexible installations requiring repeated bending.
4. Uniform Diameter & Surface Quality
Precision drawing ensures consistent diameter and a smooth, oxide-free surface, which simplifies welding, crimping, and insulation processes during sensor assembly.
5. Versatile Compatibility
Fully compatible with all standard Type K thermocouple accessories, including connectors, terminal blocks, and extension wires, allowing seamless integration into new or existing measurement systems.
