Nichrome wire is a high-resistance alloy composed primarily of nickel (Ni) and chromium (Cr). It is widely used in industrial heating applications due to its excellent thermal stability, corrosion resistance, and predictable electrical resistance. For B2B buyers in sectors such as manufacturing, laboratory equipment, and HVAC systems, understanding its properties and sourcing considerations is crucial for efficient procurement and long-term reliability.
The most common grades are NiCr 80/20 (80% nickel, 20% chromium) and NiCr 60/15. These alloys form a stable, protective layer of chromium oxide when heated, allowing them to maintain performance even under cyclic thermal loads.
| Property | Description |
|---|---|
| Electrical Resistivity | 1.10–1.18 µΩ·m at 20°C |
| Maximum Operating Temperature | Up to 1200°C (2192°F) |
| Melting Point | 1400°C (2552°F) |
| Oxidation Resistance | Excellent in air and neutral atmospheres |
| Magnetism | Non-magnetic |
Nichrome wire is essential in various high-temperature environments. Below are typical industrial sectors that require high-quality resistance wire:
Electric furnaces and kilns
Cartridge and tubular heaters
Laboratory heating elements
Foam cutters and hot-wire tools
HVAC defrosting systems
Consumer appliances (e.g., toasters, dryers)
As a steel material supplier, offering detailed and accurate specifications can significantly improve buyer confidence and conversion.
| Parameter | Typical Range |
|---|---|
| Diameter | 0.02 mm – 2.00 mm |
| Resistance (Ω/m) | Depends on gauge; typically 1.15–28 Ω/m |
| Surface Finish | Bright, oxidized, or annealed |
| Packaging | Plastic spools, coils, or custom export reels |
| Certifications | ISO9001, RoHS, REACH (on request) |
Technical Requirements: Confirm resistance, temperature stability, and alloy grade before quoting.
MOQ and Sample Policy: Many factories offer trial samples starting from 1kg for lab testing or prototype use.
Documentation: Request material certificates, SDS sheets, and export licenses if required.
Delivery Capability: Inquire about lead time, production capacity, and packaging standards for international shipping.
NiCr 80/20 offers higher resistance and better oxidation resistance, making it more suitable for high-temperature applications. NiCr 60/15 is less resistant and used where cost is a factor.
Yes. Nichrome is specifically designed for stability and reliability in continuous heating environments up to 1200°C.
Absolutely. We support custom diameters, resistance values, and packaging formats tailored to your design or equipment requirements.
Yes. Our company has exported to over 40 countries, complying with international standards such as ISO, RoHS, and REACH. Export documentation is fully supported.
For standard products, delivery is usually within 7–10 days. For custom orders, it may take 12–15 days depending on complexity and volume.
