NiCr 2080 Ultra Thin Wire – Stable Performance for Precision Resistors and Micro Heating Elements

NiCr 2080 (80% nickel, 20% chromium) is a premium alloy widely adopted in precision resistors, temperature sensors, micro‑heaters, and automotive exhaust sensors. Its key advantages – stable electrical resistivity, excellent oxidation resistance up to 1000°C, and good ductility – make it irreplaceable in demanding electronic and thermal management applications.

For resistor manufacturers, consistent resistivity is the top priority. Our ultra thin NiCr 2080 wire, available from 0.01mm to 0.2mm, offers a resistivity tolerance of ±2%, ensuring uniform heating or signal output across thousands of components. The smooth surface finish minimizes hot spots and reduces the risk of short circuits during potting or encapsulation.

In micro‑heater applications, the wire must withstand rapid thermal cycling without cracking or drifting in resistance. Our optimized annealing process refines the grain structure, enhancing both high‑temperature strength and fatigue life. We also adjust the drawing parameters to achieve specific resistance values per metre, eliminating the need for post‑production trimming.

We support custom packaging – spool sizes and protective coating – to suit automated assembly lines. Every batch is tested for tensile strength, elongation, resistivity, and surface quality.

Whether you are developing a new sensor prototype or ramping up production, our NiCr 2080 ulrtra thin wire delivers consistent, reliable performance. Contact us to discuss your specifications.
