Charge carriers for high temperature furnaces.

Charge carrier for high temperature furnaces

Our charge carriers, which we manufacture from refractory metals, do not suffer from any deformation even at high temperatures. They are stronger than graphite products and, unlike graphite, they are extremely pure and therefore well-suited for high-vacuum processes.

Our team, which uses a variety of simulation and computational methods, is able to develop the optimum design for your specific application and will choose the most suitable material. We can manufacture tailor-made charge systems for your furnace using the following components:

  • Hearth components such as rails, pins and caps
  • Insertable, screw-fastened or riveted racks
  • Stackable charge carriers with fixed or variable spacings
  • Base plates and boats for continuous furnaces
  • Intermediate plates and frames

We are also happy to supply the plates used in our charge carriers with ceramic coatings. These ensure that absolutely nothing adheres to and remains present on the surface. We design our charge systems to exhibit a high level of dimensional stability combined with the lowest possible weight.

The right mix for even greater dimensional stability.

Alongside molybdenum and tungsten, we primarily manufacture our charge equipment from TZM and ML. The creep resistance of these alloys is ten times better than that of pure molybdenum and they are also exceptionally ductile. As a result, our charge systems are perfectly equipped to cope with frequent changes between high and low temperatures. The benefit to you? A particularly long service life with barely any distortion.

By using suitable alloys and optimized production processes, we are able to improve the properties of molybdenum. To achieve a particularly high level of ductility and creep resistance, we dope pure molybdenum with small quantities of La2O3. The stabilized microstructure and modified recrystallization behavior prevent the premature embrittlement and fracture of our furnace components.


What makes ML better than pure molybdenum?

  • Higher recrystallization temperature
  • Elongated grain structure for improved ductility
  • Greater creep resistance

Whenever materials have to meet special challenges, we add titanium and zirconium to strengthen the microstructure of pure molybdenum. Mo-Ti solid solution and Ti-Zr carbides ensure that optimum strengths are achieved at temperatures up to 1 400 °C (2552 °F).


What can TZM do better than pure molybdenum?

  • Better creep resistance
  • Higher recrystallization temperature
  • Greater thermal stability
