As a high-efficiency heating element in ceramic heaters, fe-cr-al wire has the following performance advantages:
1. High temperature stability
Fe-Cr-Al heating wire can work stably in an atmospheric environment up to 1400°C. This high temperature stability far exceeds that of nickel-chromium wire Cr20Ni80 (its maximum operating temperature is 1200°C). This feature gives fe-cr-al wire a significant advantage in the high-temperature industrial field, ensuring that ceramic heaters can work stably for a long time in a high-temperature environment and maintain unchanged performance.
2. Corrosion resistance
A dense Al2O3 oxide film will form on the surface of the iron-chromium-aluminum alloy. The oxide film is tightly bonded to the substrate and is not easy to peel off, thereby effectively reducing the possibility of contamination. In addition, the high resistivity and melting point characteristics of Al2O3 make its oxide film exhibit excellent oxidation resistance. fe-cr-al wire also has excellent corrosion resistance, especially in sulfur-containing atmospheres and certain controlled atmospheres, and its corrosion resistance is better than other unoxidized materials. This allows fe-cr-al wire to be used in harsh environments and is not easily corroded, thereby extending the service life of the ceramic heater.
3. High electrothermal conversion efficiency
fe-cr-al wire has high resistivity and excellent heat resistance, and can quickly convert electrical energy into thermal energy after power is turned on. This allows the ceramic heater to heat up quickly and reach the set temperature, thereby improving work efficiency. In addition, the thermal efficiency of fe-cr-al wire can reach more than 90%, which can save a lot of energy and electricity expenses compared to traditional electric heating wire heaters.
4. Economical
Since iron-chromium-aluminum alloy does not contain the scarce element nickel, its price is much more affordable than nickel-chromium materials. This makes the application of fe-cr-al wire in ceramic heaters more economical and reduces production costs.
5. Good processing performance
Fe-chromium-aluminum alloy has good processing performance and can meet the heating needs of different shapes and sizes. This makes fe-cr-al wire more flexible in the manufacturing process of ceramic heaters and can be customized according to specific application scenarios and needs.
6. Long life characteristics
In the same atmospheric environment, the service life of Fe-Cr-Al heating wire can reach two to four times that of Ni-Cr wire. This enables Fe-Cr-Al wire to operate stably for a long time when used as a heating element of ceramic heater, reducing the frequency of replacement and maintenance costs.
As an efficient heating element in ceramic heaters, Fe-Cr-Al wire has multiple advantages such as high temperature stability, corrosion resistance, high electrothermal conversion efficiency, economical and affordable, good processing performance and long life characteristics. These advantages make Fe-Cr-Al wire widely used in the ceramic heater industry and become the preferred material of many manufacturers.
