Ni80Cr20 is a nickel-chromium alloy (NiCr alloy) characterized by high resistivity, good oxidation resistance and very good form stability. It is suitable for use at temperatures up to 1200°C,and hold a superior service life compared to Iron chromium alumium alloys.
Typical applications for Ni80Cr20 are electric heating elements in home appliances,industrial furnaces and resistors(wirewound resistors,metal film resistors), flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.

The clever design sports high peel strength and substrate rigidity, paired with low shrinkage and excellent creep consistency, resulting in reliable repeatability and minimal hysteresis. A special cover layer enhances sealing, safeguarding the sensor's performance and making it well-suited for sensitive applications requiring stability, such as C3 level precision tasks.
Calibration is a breeze, as heat treatment allows fine-tuning of the temperature characteristic sensitivity coefficient. This adaptability makes our material perfect for non-external compensation sensors operating with a tight tolerance range of 0.03% to 0.05%.
By streamlining these two versatile materials' properties, we've developed a product that doesn't just meet but exceeds the demanding requirements for precision sensor systems. Choose our laminate for an uncompromised, stable, and protected sensing experience.
