What is the best thermocouple for molten aluminium?

For molten aluminium, Type K and Type N thermocouples are most common. However, the protection tube material, such as Silicon Nitride or FerroSafe® lances, is the most critical factor for sensor longevity.

How do you protect thermocouples from molten metal corrosion?

Using specialized protection tubes like Sialon, Silicon Carbide, or FerroSafe® coatings prevents molten metal from chemically attacking the thermocouple wires, ensuring a longer service life.
