Product Description
KPKN Thermocouple Strip Type K Thermocouple Alloy Strip
KPKN thermocouple strip (0.15mm thickness × 30mm width) from Huona New Material is a precision cold-rolled alloy strip engineered for high-sensitivity Type K thermocouple sensors and miniature temperature probes. Composed of KP (Chromel, positive pole) and KN (Alumel, negative pole) alloy pairs, it delivers stable thermoelectric output, excellent formability, and consistent performance across extreme temperatures.
Standard Designations & Core Specifications
- Product Name: KPKN Thermocouple Strip (Type K Thermocouple Alloy Strip)
- Alloy Composition: KP (Positive Pole): Chromel (Ni: 89-91%, Cr: 9-11%, trace elements controlled) KN (Negative Pole): Alumel (Ni: 94-96%, Al: 1.8-2.2%, Mn: 1.8-2.2%, Si: 0.8-1.2%)
- Dimensions: Thickness: 0.15mm (tolerance: ±0.004mm) Width: 30mm (tolerance: ±0.1mm) Form: Coil (standard: 150m/roll; custom cut-to-size sheets available)
- Key Thermoelectric Performance: Thermoelectric power (at 100℃): 40.4-40.6μV/℃ (meets IEC Class 1 accuracy) Operating temperature range: -270℃ ~ 1250℃ (continuous; short-term up to 1300℃)
- Compliant Standards: IEC 60584-1, ASTM E230, GB/T 4989, ISO 9001, RoHS 2.0
- Manufacturer: Huona New Material (Shanghai) Co., Ltd.
Key Core Advantages
Ultra-Precise Thermoelectric Stability
- Class 1 Accuracy: Strictly calibrated to match Type K thermocouple standards, ensuring minimal measurement drift (<0.1℃) across long-term use
- Wide Temperature Compatibility: Performs reliably from cryogenic (-270℃) to ultra-high-temperature (1250℃) environments
Enhanced Formability for Miniature Sensors
- Thin-Gauge Flexibility: 0.15mm thickness enables easy stamping, bending, and laser cutting into miniature probe tips
- High Ductility: Elongation ≥28% (KP/KN), reducing cracking during complex forming operations
Uniform Microstructure & Consistency
- Precision Cold Rolling: Tight thickness/width tolerances ensure uniform thermoelectric response across the entire coil
- Stress-Relief Annealing: Controlled annealing process removes residual rolling stress, preventing warping
Advanced Environmental Resistance
- High-Temperature Oxidation Resistance: KP/KN alloys form dense protective oxide layers at >1000℃
- Corrosion Resistance: Excellent resistance to atmospheric corrosion and mild chemical exposure
Versatile Joining & Integration
- Weldability: Compatible with resistance spot welding, laser welding, and soldering
- Compatibility: Works seamlessly with standard Type K thermocouple connectors and industrial temperature controllers
