The combination of key properties that alumina tubes and rods offer makes them a cost-effective yet high-performance solution that can be used in a wide variety of applications across numerous industries. An alumina rod is thermally stable. It can be used in both oxidizing and reducing atmospheres up to 1600°C and in vacuum furnaces up to 1750°C. Alumina is also chemically inert and is not corroded by water or steam, offering good resistance to strong acids and alkalis at elevated temperatures. Alumina is also widely used as an electrically insulating material, especially is environments operating at elevated temperatures such as furnace lead-in tubes, and fuel-cells.
