High Light KPKN thermocouple strip type Kthermocouple alloy strip 0.2x20mmdurable temperature monitoring thermocouple strip
KPKN Thermocouple Strip (Type K Thermocouple Alloy Strip)
KPKN thermocouple strip from Huona New Material is a precision cold-rolled alloy strip specifically designed for Type K thermocouple sensors and heating elements. It consists of two matching alloy strips: KP (Chromel, positive pole) and KN (Alumel, negative pole), which together form the core of Type K thermocouples. Manufactured via precision cold rolling and vacuum annealing, it delivers stable thermoelectric properties, excellent mechanical strength, and consistent performance across a wide temperature range.

Standard Designations & Core Specifications
  • Product Name: KPKN Thermocouple Strip (Type K Thermocouple Alloy Strip)
  • Alloy Composition: KP (Positive Pole): Chromel (Ni: ~90%, Cr: ~10%)
    KN (Negative Pole): Alumel (Ni: ~95%, Al: ~2%, Mn: ~2%, Si: ~1%)
  • Typical Dimensions: Thickness: 0.20mm (customizable: 0.05-3.0mm)
    Width: 20mm (customizable: 5-300mm)
    Form: Coil (standard: 100m/roll; cut-to-size sheets available)
    Tolerance: Thickness ±0.005mm, Width ±0.1mm
  • Key Thermoelectric Performance: Thermoelectric power (at 100℃): ~40.5μV/℃ (matches Type K standard)
    Operating temperature range: -200℃ ~ 1200℃ (continuous)
  • Compliant Standards: IEC 60584-1, ASTM E230, GB/T 4989, RoHS 2.0
  • Manufacturer: Huona New Material (Shanghai) Co., Ltd., certified to ISO 9001 and IATF 16949

Key Core Advantages
Stable Thermoelectric Performance
  • Precise Thermoelectric Output: Strictly matches the Type K thermocouple standard, ensuring accurate temperature measurement with minimal drift
  • Wide Temperature Range: Performs reliably from cryogenic temperatures (-200℃) up to high-temperature industrial environments (1200℃)
Excellent Mechanical Properties
  • High Strength & Ductility: Tensile strength ≥650MPa, elongation ≥25%, enabling easy stamping, bending, and forming into complex sensor shapes
  • Good Fatigue Resistance: Withstands repeated thermal cycling without cracking or performance degradation, ensuring long service life
Uniform Quality & Consistency
  • Precision Rolling: Tight thickness and width tolerances ensure uniform thermoelectric response across the entire strip
  • Controlled Annealing: Vacuum annealing eliminates residual stress, ensuring stable mechanical and thermoelectric properties
Versatile Processability
  • Easy Forming: Compatible with stamping, bending, punching, and riveting to produce thermocouple junctions and sensing elements
  • Weldability: Suitable for resistance welding, argon arc welding, and soldering, enabling seamless integration into thermocouple assemblies
Reliable Environmental Resistance
  • High Oxidation Resistance: KP and KN alloys exhibit excellent oxidation resistance at high temperatures, suitable for harsh industrial environments
  • Corrosion Resistance: Good resistance to atmospheric corrosion and mild chemicals, extending service life in industrial and laboratory settings
