Features
- FeCrAl alloy has a high melting point, typically above 1400°C, and can maintain stable performance at 1200°C for extended periods.
- At high temperatures, the aluminum in the alloy forms a dense aluminum oxide (Al₂O₃) protective film, which prevents further oxidation and enhances durability.
- The material exhibits low volatility and strong sulfur resistance, ensuring long-term stability while reducing material loss and replacement frequency.
- It has high resistivity with minimal resistance variation at elevated temperatures, making it highly suitable for heating applications.
- Compared to Nickel-Chromium alloys, FeCrAl alloy offers similar or superior performance at a lower cost, providing a more cost-effective solution for industrial heating applications.
Applications
- Industrial furnaces: Used as heating elements in melting furnaces, annealing furnaces, and other high-temperature systems
- Household appliances: Commonly found in ovens, heaters, and portable electric heating devices
- Far-infrared devices: Utilized for efficient heat radiation applications
