FAQs
A: 0Cr25Al5 (also 1Cr25Al5 or Cr25Al5) is a high-resistivity iron-chromium-aluminium (Fe-Cr-Al) electrothermal alloy strip developed and manufactured in China. It has almost identical chemical composition and performance to Swedish Kanthal D, reaching maximum service temperature of 1300–1350°C, which makes it the most popular Kanthal-grade replacement in China and worldwide.
A: It is widely used in industrial electric furnaces, kiln heating elements, ceramic kilns, glass melting furnaces, heat-treatment furnaces, infrared heaters, resistor braking systems, and high-power household appliances.
A: The continuous service temperature can reach 1300°C, with short-term maximum temperature up to 1350°C, far exceeding traditional NiCr 80/20.
A: Compared with Nichrome, 0Cr25Al5 offers 2–4 times longer service life at the same temperature, better oxidation resistance, lower density (meaning lighter weight for the same resistance), and 20–40% lower material cost – making it the preferred high-temperature heating element material in China and globally.
A: Yes. Thanks to its stable resistivity (1.45 ± 0.05 μΩ·m) and low temperature coefficient of resistance, it is widely used in high-power braking resistors, neutral grounding resistors, and load bank resistors.
