Kanthal Super ER is a new electric heating element with the unique ability to operate up to 1580°C (2875°F) directly in a wide range of furnace atmospheres from very dry reducing to oxidizing. With Kanthal Super ER heating elements it is possible, in just one furnace, to operate firing cycles where the atmosphere condition can be altered, during the cycle, between oxidizing, inert, carburizing, nitriding, reducing and rough vacuum.
The major reason for the new and outstanding features of Kanthal Super ER heating elements is that it has a protective surface of pure alumina. The alumina layer grows on the surface of the heating element at high temperatures even in dry hydrogen. The elements can work in direct contact with high alumina supports without corrosive reactions.
Kanthal Super ER heating elements cover a wide range of furnace atmospheres and processes. Most types of PM sintering in dry hydrogen and furnace with alternating oxidizing and reducing atmospheres. Continuous furnace with hydrogen atmospheres for ferrite sintering and MLCC processing.
