Nickel-Chromium 80/20 Wire (NiCr 80/20 Wire)​

A high-performance alloy wire (80% Ni, 20% Cr) designed for high-temperature and electrical applications, ideal for demanding industrial and consumer scenarios.​
Key Features​
  • High-Temp Stability: Operates continuously at up to 1,100°C (2,012°F); short-term peak at 1,250°C (2,282°F).​
  • Oxidation Resistance: Forms a protective Cr₂O₃ film to resist corrosion in cyclic heating.​
  • Stable Resistivity: ~1.10 Ω·mm²/m (20°C) for uniform heat generation, no hot spots.​
  • Good Ductility: Easy to fabricate (draw, coil) while retaining strength at high temps.​
Core Advantages​
  • Long service life reduces maintenance costs.​
  • Energy-efficient heat conversion (minimizes waste).​
  • Versatile for custom forms (fine wire, coils, ribbons).​
  • Cost-effective vs. alternatives in long-term high-heat use.​
Typical Applications​
  • Industrial: Furnace/oven heating elements, plastic molding tools.​
  • Household: Electric stoves, toasters, water heaters.​
  • Automotive: Seat heaters, defrosters.​
  • Aerospace/Medical: Avionics thermal management, sterilization equipment.
