Furnace Heating Element Materials

Before beginning our comparison of heating element materials let s take a moment to point out that when rating the materials for maximum temperature we are referring to the maximum element temperature not the maximum furnace temperature.

Furnace heating element materials. Our heating elements outperform in all temperature ranges from element temperature 50 to 1850 c 120 3360 f and atmospheres. Resistivity at 20 o c. High resistance to oxidation. While most ceramics have a negative coefficient these materials often barium titanate and lead titanate composites have a highly nonlinear thermal response so that above a composition.

Kanthal super molybdenum disilicide mosi 2 heating elements for element temperatures up to 1850 c 3360 f. Temperature coefficient of resistance at 20 o c. Kanthal products are designed for extremely high temperatures in reducing carburizing and nitriding neutral and oxidizing atmospheres contributing to maximized heat flux and reduction of process time. Ptc ceramic materials are named for their positive thermal coefficient of resistance i e resistance increases upon heating.
