Kanthal is a world-leading brand for products and services in the area of industrial heating technology and resistance materials.

Kanthal Super 1900 (Molybdenum disilicide)

Datasheet updated 2010-05-11 13:30:51 (supersedes all previous editions)

Kanthal Super is a unique material combining the best properties of metallic and ceramic materials. Like metallic materials it has good heat and electric conductivity and like ceramics it withstands corrosion and oxidation and has low thermal expansion. It is not affected by thermal shock and is strong enough to withstand many years of service as a heating element.

Typical area of application for Super 1900 includes laboratory furnaces, testing equipment and high temperature sintering furnaces.
