NiCr80/20 Nickel Chromium Alloy Round Wire 0.025mm To 12mm Used For Heat Sealing Machines

NiCr80/20 Nickel Chromium Alloy Round Wire 0.025mm To 12mm Used For Heat Sealing Machines

 

Ni80Cr20 (8020 nickel-chromium alloy) is a high-resistance electrothermal alloy with excellent performance. Due to its outstanding high-temperature stability and corrosion resistance, it is widely used in the manufacture of various heating elements.

 

Ultra-thin nichrome wire of 0.025 mm (25 micrometers) is typically used when you need an extremely small, fast-responding resistive element—because thinner wire has higher resistance per unit length and low thermal mass (heats/cools very quickly).

Common applications

  • Precision micro-heaters (lab and instrumentation)
  • Thermally sensitive heating elements in micro-optics / optics benches (e.g., small alignment/anti-condensation heaters)
  • Fine-wire heating for sensors, such as
    • hot-wire anemometry / airflow measurement (very thin heated wire)
    • small flow/temperature sensing probes
  • Thermal inkjet / small droplet or fluid-control heater experiments (R&D setups)
  • Electrothermal micro-devices and prototype resistive loads where very fine resolution is required
  • Thin-film replacement / calibration uses in resistance calibration setups
  • Very small nichrome coils/wicks for controlled heating (custom maker/R&D builds)
