It's pretty hot in a jet engine (sometimes above 2,200 C).


Blades and vanes mounted on a ring are charged with a burning, compressed air-kerosene mixture, which generates the thrust. Here nickel cobalt alloys with the highest possible melting point are used, which often show a high aggressiveness in the molten state. While casting the blades no external particles must enter the product and the crucible should provide repeatable performance. The requirements of the aviation industry are extremely high and demand appropriate consumables.

We supply this industrial sector for many decades and are the global market leaders here!


To achieve an optimum result, the crucible must
• be extremely temperature-resistant
• be low wetting
• not release any substance to the alloy

Therefore our zirconia crucibles are applied here.


To achieve the best performance with our products, we offer trainings in Installation and use of our crucibles.
