sales2@super-metals.comHeating Coil
We manufacture customized heating coil according to each customer’s requirements. Both Fecral (FeCrAl) and Nichrome (NiCr) heating coils are available. FeCrAl alloys (Iron-Chromium-Aluminum) are widely used materials for heating coil due to their excellent oxidation resistance, high electrical resistivity, and mechanical strength. Nichrome (Nickel-Chromium) alloys are widely used materials for heating coils due to their high resistivity, oxidation resistance, and stability at moderate temperatures.
- FeCrAl alloy heating coil available grades and comparison:
| Grade | Composition | Max Temp | Key Features | Cost |
| 0Cr23Al5 | Fe-23Cr-5Al | 1200°C | Balanced performance | Low |
| 0Cr25Al5 | Fe-25Cr-5Al | 1250°C | Best corrosion resistance | Low |
| 0Cr21Al6Nb | Fe-21Cr-6Al-Nb | 1300°C | Chinese standard (Nb stabilized) | Moderate |
| HJ209 (Kanthal A-1 Substitute) | Fe-22Cr-5.8Al | 1400°C | Standard industrial grade, High oxidation resistance, stable resistivity | Moderate |
| HJ407 (Kanthal APM Substitute) | Fe-21Cr-5Al-0.02Ce | 1425°C | Enhanced creep resistance, long lifespan | Moderate |
- Nichrome alloy heating coil available grades and comparison:
| Grade | Composition | Max Temp | Key Properties | Best Applications |
| Nichrome 80 | 80% Ni, 20% Cr | 1,200°C | High ductility, stable resistance, excellent oxidation resistance | Toasters, hair dryers, heating elements |
| Nichrome 70/30 | 70% Ni, 30% Cr | 1,250°C | Higher resistivity, slightly less ductile | Industrial heaters, high-power applications |
| Nichrome 60 | 60% Ni, 16% Cr, 24% Fe | 1,150°C | Cost-effective, good for moderate temps | Cheap heating coils, low-cost appliances |
- Temperature & Performance:
| Property | Fecral | Nichrome |
| Resistivity | Higher | Lower |
| Ductility | Less ductile (harder to coil tightly) | More flexible (easier to shape) |
| Lifespan at High Temp | Longer (better for continuous high-heat use) | Shorter (degrades faster above 1,000°C) |
| Cold/Warm Resistance | Small change (stable) | Larger change (resistance varies more with temp) |
- Cost & Availability:
| Factor | Fecral | Nichrome |
| Cost | Lower grades cheaper (no nickel content) | More expensive (nickel prices fluctuate) |
| Availability | Widely available (common in industrial heating) | Very common (used in consumer electronics) |
- Best Applications:
| Fecral (FeCrAl) Coils | Nichrome (NiCr) Coils |
| Industrial furnaces (high-temp) | Household appliances (toasters, hair dryers) |
| Long-duration heating (kilns, ovens) | Precision heating (lab equipment) |
| Corrosive/sulfur-rich environments | Applications needing tight coiling |
| Cost-sensitive high-temp projects | Moderate-temp, high-flexibility uses |
Which One to Choose?
– Pick Fecral if: You need higher temperatures, longer lifespan, or corrosion resistance (e.g., industrial furnaces, high-wattage heaters).
– Pick Nichrome if: You need easier shaping, stable resistance, or moderate heat (e.g., consumer electronics, small heating elements).
