Because of the characteristics of the material itself, resistance wires made of different materials have different application scenarios. For example, iron-chromium-aluminum alloy is a material commonly used in the manufacture of resistance wires. So what are the characteristics of resistance wires made of iron-chromium-aluminum alloy? In what scenarios is it generally used?
1. High temperature strength: Iron-chromium-aluminum alloy has high strength at high temperatures, can maintain good mechanical properties, and is not prone to deformation.
2. High operating temperature: The maximum operating temperature of the iron-chromium-aluminum alloy resistance wire can reach about 1400℃, which is suitable for heating needs in high temperature environments.
3. Long life: Compared with some other materials, Fe-Cr-Aluminum alloy resistance wire has a longer service life and can work stably under high temperature conditions.
4. High surface load: Due to the advantage of high temperature strength, Fe-Cr-Aluminum alloy resistance wire can have a higher surface load, so that more heat can be output per unit area.
5. Anti-oxidation performance: The oxide film (mainly aluminum oxide) formed on the surface of the iron-chromium-aluminum alloy is dense and has good oxidation resistance, which helps to slow down the oxidation rate of the resistance wire.
6. Smaller specific gravity: The specific gravity of iron-chromium-aluminum alloy is relatively small, which means that the resistance wire of the same quality can provide a longer length, which is conducive to the design of some special application scenarios.
7. Higher resistivity: The resistivity of Fe-Cr-Aluminum alloy is relatively high, which allows the selection of alloy materials with larger diameters when designing resistance wires, helping to extend the service life of components.
8. Good anti-sulfur performance: Iron-chromium-aluminum alloy has good corrosion resistance in sulfur-containing atmosphere and environment where the surface is contaminated by sulfur-containing substances.
9. Relatively low price: Compared with some rare metal alloys, the cost of Fe-Cr-Al alloy is relatively low, making it more competitive from an economic perspective.
In general, iron-chromium-aluminum alloy resistance wire is widely used in electric heating applications under high temperature environment due to its high temperature strength, oxidation resistance, long life and other characteristics.Resistance Wire Manufacturers, you can chooseRaytronAs a professional resistance wire manufacturer in China, Ruichuang has professional production personnel, advanced production equipment, and can deliver goods in time.
