Ceramic carbon composites provide ideal properties where it comes to reliable function and longevity in harsh environments and at high temperatures.

We bring decades of experience with ceramic composites to additive manufacturing in order to provide our customers the opportunity to realize almost any design with ceramic carbon composites. CARBOPRINT Si components are made by siliconizing CARBOPRINT C bodies.

The advantages of CARBOPRINT® Si are:

  • Low weight due to low density
  • High thermal shock resistance
  • High bending strength
  • High wear resistance

This material data has been provided by SGL Carbon.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
