Contact us

Kanthal Super MoSi2 heating elements are available as straight or bent elements in a wide range of sizes and shapes. The most commonly used design is a two-shank "U"-shaped element. The heating zone is welded to terminals which normally have a diameter double that of the heating zone. The two-shank element can be bent 45° or 90° either in the heating zone or in the terminals.

We also provide special designed elements according to customer needs.
