Because of the characteristics of the material itself, different materials have different applications for resistance ribbons. For example, ferrochrome-aluminium alloy is a material commonly used in the manufacture of resistance ribbons. What are the characteristics of resistance ribbons made of ferrochrome aluminium alloy? In which scenarios is it commonly used?
1. High-temperature strength:
Iron-chromium-aluminium alloy has high strength at high temperatures, which can maintain good mechanical properties and is not easy to be deformed.
2. High operating temperature:
the maximum operating temperature of the iron chrome aluminium alloy resistance ribbon can reach 1400 ℃ or so, suitable for high-temperature environment heating needs.
3. Long service life:
Compared with some other materials, FeCrAl alloy resistance ribbon has a long service life and can work stably under high temperature conditions.
4. High surface load:
due to the advantage of high temperature strength, the iron chrome aluminium alloy resistance ribbon can have a high surface load, so that more heat can be output per unit area.
5. Antioxidant performance:
the oxide film (mainly aluminium oxide) generated on the surface of FeCrAl alloy is dense and has good antioxidant property, which helps to slow down the oxidation speed of the resistance ribbon.
6. Smaller specific gravity:
The specific gravity of FeCrAl alloy is relatively small, which means that the same quality of resistance ribbon can provide greater length, which is conducive to the design of some special application scenarios.
7. Higher resistivity:
The relatively high resistivity of FeCrAl alloy means that a larger diameter alloy can be selected when designing the resistance ribbon, which helps to extend the service life of the component.
8. Better sulphur resistance:
In the sulphur-containing atmosphere and surface contaminated by sulphur-containing substances, FeCrAl alloy has better corrosion resistance.
9. Relatively low price:
Compared with some rare metal alloys, the cost of ferrochromium-aluminium alloy is relatively low, making it more competitive in economic considerations.
Overall, FeCrAl alloy resistance ribbon is widely used in electric heating applications in high temperature environments due to its high temperature strength, oxidation resistance and long life.
