High Light	Type K Chromel-Alumel thermocouple strip ，ultra-thin flat thermocouple tape ，micro precision alloy temperature sensor

Product Overview

This micro-thin Type K Chromel-Alumel flat thermocouple strip from Huona is a lightweight precision alloy material specially engineered for compact, miniature temperature detection assemblies. Matched with standard Chromel positive and Alumel negative thermocouple alloys, the strip adopts ultra-fine cold rolling and stress-free bright annealing production technology, featuring ultra-thin uniform cross-section, silky smooth mirror surface, ultra-low internal residual stress and consistent thermoelectric conversion efficiency. It is designed for narrow-space installation scenarios, micro-sized patch sensors and miniature thermal testing fixtures, delivering precise, repeatable temperature signals even under confined assembly and frequent slight bending cycles.

Core Specifications

Product Name: Type K Chromel-Alumel Micro Ultra-Thin Flat Thermocouple Strip

Conductor Material: Positive (Chromel / KP Ni-Cr Micro Alloy) / Negative (Alumel / KN Ni-Si-Mn Micro Alloy)

Processing Technology: Ultra-fine micro rolling + stress-free bright annealing + micro edge trimming

Standard Specification: 0.08mm Thickness × 1.5mm Width

Customizable Size Range: Thickness 0.04–0.35mm, Width 0.6–7.0mm

Surface Condition: Superfine mirror bright surface, micro burr-free edges, no oxidation spots or streaks

Thermoelectric Performance: Batch calibrated to international IEC Type K thermocouple criteria, ultra-low thermal voltage drift

Operating Temperature Range: -200°C ~ 1260°C (stable continuous operation under dry oxidizing environments)

Standards Compliance: IEC 60584-2, GB/T 4989, RoHS 2.0, REACH low-hazard material certification

Key Differentiating Advantages

1. Micro-Grade Paired Chromel-Alumel Alloy Composition

This ultra-thin flat strip uses high-purity refined Chromel and Alumel raw materials with tightly controlled trace element content. Each production lot undergoes individual thermoelectric matching calibration to guarantee linear signal output across the full working temperature band. Minimal component deviation eliminates measurement inaccuracies, perfectly matching the high consistency demands of mass miniature sensor manufacturing.

2. Excellent Low & Medium Temperature Oxidation Resistance

The refined alloy grain structure significantly enhances oxidation resistance under low to medium temperature working conditions. It avoids rapid surface oxide layer generation during long-term mild heating cycles, maintaining stable thermoelectric performance without performance attenuation, greatly extending the service life of tiny built-in temperature sensing components.

3. Super-Flexible Micro-Thin Machining Performance

Stress-free annealing removes internal processing tension, granting the strip outstanding softness and bending resilience. It withstands ultra-tight radius winding, micro stamping and ultra-fine cutting without fracture or rebound deformation. Its slim flat profile fits narrow gaps and curved contact surfaces to capture high-sensitivity temperature feedback in limited installation space.

4. Micro-Tight Dimensional Consistency & Premium Surface Finish

Adopting micron-level closed-loop rolling and precision slitting equipment, the strip achieves ultra-narrow dimensional tolerance on thickness and width. The polished mirror surface reduces thermal contact resistance, while trimmed smooth edges prevent insulation scratching during sensor encapsulation, fully meeting the strict precision standards of miniaturized electronic thermal modules.

5. Stable Adaptability for Light-Duty Cyclic Working Conditions

This ultra-thin Chromel-Alumel alloy tape boasts outstanding thermal fatigue resistance against frequent temperature fluctuations. It sustains steady mechanical and thermoelectric properties under intermittent short-cycle temperature monitoring, offering reliable sensing performance for portable testing devices, compact heating elements and precision electronic equipment.
