Oxide Fiber Composites - Durafox®

For corrosive and oxidative environments

Durafox® - our oxide fiber composites

Extreme exposure to corrosive or oxidative environments is a major challenge for auxiliary equipment or equipment components. Thanks to their outstanding material-specific property profile, components made of Oxide Fiber Composites (OFC) have enormous potential for just such applications.

What makes our Durafox® OFCs stand out?

The unique microstructure of the oxide fiber composite combines metallic and ceramic properties in one material, thus defying the known limitations of ceramics. While technical and conventional ceramic materials exhibit very brittle fracture behavior and shatter when subjected to thermal shock and impact, Durafox® impresses with its ductility. Our Durafox® ceramics have high damage tolerance and thermal shock resistance and, depending on the material variant, are designed for temperatures of up to 1,300 °C in continuous use. Unlike graphite and CFRC, Durafox® does not oxidize, which allows it to be used under oxidizing conditions. Components made of OFC are the safe solution thanks to the outstanding material properties. Our customers benefit from a large selection of materials and production methods.

Where are our Durafox® oxide fiber composites used?

Our OFCs are virtually predestined for many areas of application. For example, they can be used in high-temperature applications under air, in inert or reduced atmospheres as carburization protection for CFRC racks or under oxidizing conditions as all-oxide fixtures for heat treatment, as protective layers in sintering processes under reducing atmospheres, in sintering boxes for powder treatment and in nozzle technology in the aerospace industry. Our Durafox® OFCs are also used as burner nozzles in furnace building and for charging and transporting liquid aluminum alloys in the foundry industry.
