CeramTec's Advanced Ceramics for the Automotive Industry


Environmental concerns, safety, technological advances, and changes in government regulations are only a few challenges facing the automotive industry. Those within the automotive manufacturing industry must be able to face these challenges through process improvement and the use of new, innovative materials. Advanced ceramics contain exceptional properties for extremely stringent demands on durability and resilience. CeramTec's proficiency in the complex manufacturing process of advanced ceramics and its leadership in developing and integrating ceramics components for complex systems create a perfect fit for the future of the automotive industry. Extreme durability and wear resistance, low weight, high heat and corrosion resistance, heat conductivity, and thermal or electrical insulation are demands facing the automotive industry. These demands are met to perfection by advanced ceramics parts and components manufactured by CeramTec.

Engine components are exposed to the highest stress and many other factors through temperature fluctuations, splashing water and shocks. These are perfect situations for materials and systems technology offering the highest performance. Ceramic materials can be very lightweight and extremely heat, wear and corrosion resistant. With great reliability, they perform critical tasks where conventional materials fail. MMC composites as well as structural ceramics offer design engineers new perspectives in lightweight engine production. In engines heat-resistant ceramic parts like valve components, backings in the crankshaft housing and components for gasoline and water pumps ensure increased efficiency, less wear and lower noise emission.

CeramTec's advanced ceramics play a vital role in increasing safety, cost-effectiveness and comfort in vehicle engineering. CeramTec's LED lighting systems with ceramic components significantly improve visibility and protective ceramics deliver the required safety.
