Product Description
Product Overview
This balanced-performance Type K Chromel-Alumel flat thermocouple strip from Huona is a versatile general-purpose sensing alloy designed for multi-scenario industrial temperature measurement. Equipped with perfectly matched Chromel positive and Alumel negative alloy conductors, the strip adopts medium-spec precision rolling and balanced-hardness semi-soft annealing craft. It delivers moderate tensile strength and great bending flexibility, with uniformly glossy surface, consistent thickness and width tolerance, plus steady thermoelectric conversion performance. Packaged with transparent protective film wrapping on plastic spools as shown in the picture, it avoids surface scratches during transit and storage, suitable for mass production of standard surface thermocouples, general equipment temperature monitoring parts and multi-purpose thermal detection probes for factories and test workshops.

Key Differentiating Advantages
1. Universally Matched Chromel-Alumel Standard Alloy Pair
This flat strip adopts widely recognized industrial standard Chromel-Alumel alloy formula with strict raw material impurity control. Every batch undergoes full thermoelectric calibration to maintain linear voltage output throughout the whole temperature range, minimizing measurement deviation for daily industrial detection. Stable batch-to-batch consistency reduces adjustment work during sensor mass production, ideal for general standardized sensing component manufacturing.
2. Balanced High & Medium Temperature Anti-Oxidation Ability
With balanced alloy grain distribution, the material maintains reliable oxidation resistance at both medium and sub-high working temperatures. It slows oxide layer accumulation under regular cyclic heating and cooling, preventing gradual loss of sensing precision, and extends the service cycle of general-purpose thermocouple probes for conventional heating equipment.
3. Dual Balanced Mechanical Property: Strength & Flexibility
Semi-soft annealing achieves an ideal balance of tensile strength and bendability. The strip resists stretching breakage during assembly while supporting frequent winding, laminating and punching without cracking or rebound deformation. Its medium-thin flat design provides sufficient contact area for stable temperature capture without limiting installation in narrow spaces.
4. Anti-Scratch Packaged & Uniform Surface Dimensional Control
Adopting transparent plastic film full wrapping on spools, the strip surface stays intact during transportation and stock storage, avoiding scratches, dust and oxidation spots before processing. Precision rolling and slitting ensure tiny dimensional deviation across the entire reel, with smooth rounded edges that won’t damage insulation materials in sensor encapsulation procedures.
5. Wide Compatibility with Ordinary Industrial Working Environments
This Chromel-Alumel alloy flat tape possesses decent thermal shock and dry atmospheric corrosion resistance, adapting to most conventional factory thermal testing conditions including intermittent heating, frequent temperature shifts and general dry air surroundings. It sustains stable mechanical and thermoelectric parameters for long-term daily automatic temperature monitoring tasks.
