Silicon nitride automotive fuel pump seals.

Extend Powertrain Life & Reliability with Engineered Ceramics

Engine and drivetrain suppliers are using engineered ceramic components to improve the performance, lifetime, and reliability of automobile engines and drivetrains — including balls, bearings, seals, and valves.

Cerbec silicon nitride bearing balls.

Automotive Balls & Bearings

Engineered technical ceramic balls and bearings are ideal for automotive drivetrain components — helping engines run longer, smoother and cooler. Cerbec® balls and bearings made with CoorsTek silicon nitride (Si3N4) are inherently lighter, stiffer, smoother, harder, corrosion resistant, and require less lubrication than their steel counterparts. This means Cerbec bearings can run at higher speeds and higher operating temperatures with lower torque.

  • Seat belt bearings

Alumina substrate group for automotive electronic applications.

Electric Vehicle Components

Technical ceramics extend system life, improve range, and increase safety—reshaping the possible in battery electric vehicle (BEV), hybrid electric vehicle (HEV), and fuel cell vehicle (FCV) systems. CoorsTek technical ceramics provide necessary material properties such as high thermal conductivity and dielectric strength to help ensure safe and efficient operation. 

Silicon nitride hard face seal for automotive applications.

Hard Face Seal Components

In automobile fluid controls, advanced ceramic seals provide long-life, high-reliability performance. Hard face seal components are used in critical-duty applications such as:

  • Fuel pump seals
  • Water pump seals 

 

Family of foundry filters made with mullite for metal foundry filtration applications.

METAL FOUNDRY FILTERS

CoorsTek Flow-Rite® ceramic filters remove particulate from molten metal used for automotive castings such as engine blocks and heads, axle and transmission housings, and more. These thermally stable alumina-silicate components provide superior filtration of iron, aluminum, and steel castings at foundries worldwide. Learn more

Automotive salt cores for piston castings using technical ceramics.

SOLUBLE CASTING CORES

Ceramic cores are used as "salt cores" or sacrificial structures to form cavities for precise, complex shapes in automotive investment casting processes. For example, piston rings for automotive engines require precision geometries and features for low-friction, good-sealing, long-life performance  — using ceramic cores for tight tolerances and precise features. CoorsTek ceramic cores are engineered for precision tolerance, high thermal stability, low thermal expansion, and soluble removal.

 

Alumina automotive rotary side valve components.

Valves

CoorsTek engineered ceramic valve components stand up to the high-cycle, harsh environments of automobile powertrain and fluid control valve applications including:

  • Chassis leveling valves
  • Metering valve plungers
  • Fuel injector valve assemblies
  • Rotary & slide valves   

Turbocharger rotor made with silicon nitride.

Engine Components

CoorsTek engineered ceramic components are critical in the most severe automotive powertrain applications — delivering superior reliability and useful life in high temperature, high stress, and corrosive environments. Silicon nitride, for example, is inherently lighter, stiffer, smoother, harder, corrosion resistant, and requires less lubrication than steel engine component counterparts.
