Fe-Cr-Al High Temperature Heater Wire (High Temperature Alloy)

Fe-Cr-Al alloy heater wire is specifically designed for high-temperature applications and can operate continuously at temperatures up to 1,400°C. It is ideal for industries requiring excellent heat resistance and oxidation resistance, such as industrial furnaces, melting furnaces, ceramics, glass, steel, and electronics industries.

This alloy offers superior oxidation resistance compared to AF Alloy at temperatures above 1,300°C, making it highly suitable for heating applications that require long service life and stable performance.
