Durafox™ Ceramics for aluminum processing

Durafox™ Ceramics for aluminum processing

Technical parts are subjected to an extreme load during the processing of aluminum melts in heavily corrosive and oxidizing environments, while at high temperatures and subjected to great fluctuations in temperature. System parts and auxiliary agents made of Durafox™ Ceramics have a significantly higher service life under such conditions than parts made of conventional materials.

A major challenge for the foundry industry is the wear and tear and, above all, the entry of impurities by tool and system components during the processing of aluminum melts. Innovative product developments and approaches to solutions based on oxide fiber reinforced oxide ceramics can help to remedy this situation. These so-called OFC materials (oxide fiber composite) offer chemical resistance and a very advantageous wetting behavior against to molten aluminum, which eliminates the need for sizing processes and improves the quality of the castings.

You benefit from these advantages:

  • Combination of high strength and ductility under thermomechanical stress
  • Outstanding thermo-mechanical properties
  • High damage tolerance, no risk of brittle fracture
  • Excellent resistance to temperature changes
  • Corrosion and oxidation resistance
  • Chemical resistance to aluminum melts and atmospheric oxygen
  • Advantageous wetting behavior
  • No reaction with Na and Sr
  • Easy removal of solidified Al
  • Low thermal conductivity
  • Low wall thickness of the components
  • Lightweight construction due to fiber reinforcement and density < 3 g/cm³
  • No penetration of Al into porous material
