Tankii Flat Wires Made Of Nickel-Chromium Alloys Used For Home Appliance Heating Bodies
Comparison Table of Nickel-Chromium 1560 Flat Wire, Cr20Ni80 flat wire, and Iron-Chromium-Aluminum alloy flat wire:
| Item | Cr15Ni60(1560 Flat wire) | Cr20Ni80(2080 Flat wire) | FeCrAl(Cr25Al5 etc ) |
|---|---|---|---|
| Long-term use temperature | 1100℃ | 1200℃ | 1250–1350℃ |
| Resistivity | Medium-high | High | Highest |
| High-temperature strength | Good | Very Good | Poor, prone to deformation and sagging at high temperatures |
| Toughness / brittleness | Good toughness, not prone to brittle fracture | Best toughness | Prone to brittle fracture after high-temperature cooling, prone to breakage |
| Magnetism | Slight-magnetic | Non-magnetic | Weak magnetic / magnetic |
| Oxidation resistance | Good | Excellent | Very good (alumina film) |
| Sulfur resistance / corrosion resistance | General | Better | Poor, avoid processing and welding in sulfur-containing atmosphere |
| Processing and welding | Easy | Easy | general, brittle and prone to cracking |
Nickel-chromium 1560 (Cr15Ni60) is a classic high-temperature electrical heating alloy in the nickel-chromium series. Its core advantages include high resistivity, high-temperature stability, good oxidation resistance, and non-magnetic properties. In the form of flat wire, it is mainly used in scenarios such as planar/strip heating elements, industrial furnaces, and home appliance heating bodies.
1. Chemical composition (mass fraction) Ni: 58%–61% (providing high-temperature stability, corrosion resistance, and austenitic matrix) Cr: 14%–16% (forming a dense Cr₂O₃ protective film, enhancing high-temperature oxidation resistance) Fe: balance (≤8%), C≤0.1%, Si≤1.0%, Mn≤0.5%
2. Key physical/electrical properties
Density: 8.2 g/cm³
Melting point: 1380–1450℃
Resistivity (20℃): 1.04–1.12 μΩ・m (high resistivity, suitable for heat generation)
Maximum long-term use temperature: 1100–1200℃ (in air/neutral atmosphere)
Thermal expansion coefficient: approximately 12.4×10⁻⁶/℃ (20–1000℃)
Thermal conductivity: approximately 12–13 W/(m・K) (20℃)
3 .Unique Advantages of Flat Wires/Strips (Compared to Round Wires):
a . Faster Heat Dissipation and More Uniform Temperature: The flat cross-section has a large surface area, allowing heat to dissipate easily and reducing the risk of localized overheating.
b. Superior Fit and Installation: It can fit tightly against the heating surface, resulting in high heat conduction efficiency; it is easy to bend and shape, suitable for complex-shaped components.
c. Large Contact Area and Reliable Welding: The flat surface has low contact resistance, resulting in stronger welding/riveting, suitable for precision electrical appliances and sensors.
d. Fatigue Resistance and Longer Lifespan: The flat structure has better stress distribution, making it less prone to breakage under repeated on/off/thermal cycling.
e. Flexible Specifications: Thickness 0.025–2mm, Width 0.5–5mm (customizable), suitable for micro to high-power components.
