MoSi2 heating element grades

Contact us

The Kanthal program of MoSi2 heating elements includes seven grades with specific features for use in demanding applications and atmospheres, including nitrogen, hydrogen, vacuum and mixtures of endogas and reducing atmospheres.

All Kanthal Super MoSi2 heating elements are characterized by good heat and electrical conductivity. They have low thermal expansion and withstand corrosion and oxidation.

Kanthal Super MoSi2 heating elements are available as straight or bent elements in a wide range of sizes and shapes.

Grade Grade description incl. max. temperature1)

Kanthal Super 1800

Same core characteristics as Kanthal Super 1700.
Max. temperature 1800°C (3270°F)

Kanthal Super 1900

Same core characteristics as Kanthal Super 1700, but has higher purity and a surface with better adhesion.
Max. temperature 1850°C (3360°F)

Kanthal Super RA

Same core characteristics as Kanhtal Super 1700, but offers long life at high temperatures in all reducing and oxygen deficient atmospheres. Specially designed for working in nitrogen.
Max. temperature 1700°C (3090°F)

Kanthal Super ER

Same core characteristics as Kanthal Super 1700, but designed to alternate between atmospheres like oxidizing, inert, carburizing, nitriding, reducing and rough vacuum – without the need of a protecting muffle. Has a relative large power output at low temperature.
Max. temperature 1590°C (2895°F)2)

Kanthal Super HT

Same core characteristics as Kanthal Super 1700, but with better hot strength and form stability. Designed for a longer life of small dimension elements in temperature cycling conditions.
Max. temperature 1800°C (3270°F)

Kanthal Super NC

Same core characteristics as Kanthal Super 1700, but designed to meet the demands for clean process heating in the research and electronics industries.
Max. temperature 1800°C (3270°F)
