Characteristics:
Nichrome wire exhibits high electrical resistivity, excellent high-temperature endurance, and superior oxidation resistance, making it ideal for electric heating elements and industrial heating applications.
Composition:
- Nickel (Ni): 80% to 20%
- Chromium (Cr): 20% to 80%
- Trace elements (including Fe, Al, etc.) for performance optimization
Standard Alloys:
- Ni80Cr20 (80% Ni + 20% Cr, most common)
- Ni60Cr15, Ni70Cr30, Ni90Cr10
- Ni35Cr20, Ni20Cr25
Key Properties:
• High resistivity (1.0-1.5 μΩ·m) - optimal for heating elements
• Thermal stability (operating range: 1000-1400°C)
• Self-passivating oxidation layer (Cr2O3 formation)
• Excellent mechanical strength at elevated temperatures
• Extended service life in continuous high-temperature operation
Operational Guidelines:
! Critical temperature limits must be observed to prevent premature failure
! Avoid mechanical stress from excessive bending or tension
! Maintain dry storage conditions to preserve protective oxide layer
