Scaling of the element surface, which occurs in all heating elements, which occurs in all heating elements, is reduced to a minimum. The metal content is also reduced which means less diffusion into the furnace atmosphere from the element. The content of Fe, Ni and Cu (and other elements on request) can be verified and confirmed in a certificate of analysis. The electrical properties are the same as for Kanthal® Super 1800.


Kanthal® Super NC is used in all types of clean processes in the research- and electronics industries. Kanthal® Super NC is also used in diffusion furnaces for the semiconductor industry, where high purity is a demand.
