Alumina Ceramic
A practical starting point when wear resistance, electrical insulation and cost balance are important.
Zirconia Ceramic
Evaluate when higher fracture toughness, compact precision parts or fine surface quality matter.
Aluminum Nitride
A key option where heat transfer and electrical insulation must be combined in one ceramic.
Silicon Nitride
Evaluate for high-temperature strength, thermal-shock resistance and rolling-contact duties.
Boron Nitride
Useful where machinability, high-temperature electrical insulation or non-wetting behavior is important.
Machinable Glass Ceramic
A route for complex machined geometry where conventional ceramic tooling or firing routes are less convenient.
ZTA Ceramic
A material family to evaluate when alumina-like wear performance needs additional toughness.
Ceramic Substrate Materials
Material routes for electronic and thermal substrate applications, selected by system requirements.

Material × Application: Where Should You Start?
| Application Requirement | Material to Evaluate First | Why | Buyer Check |
|---|---|---|---|
| Wear resistance + electrical insulation | Alumina / ZTA | Strong starting path for wear and insulating duties with cost balance. | Confirm grade, geometry and required finish. |
| Higher fracture toughness + compact precision part | Zirconia | Useful where crack resistance and fine mechanical geometry are priorities. | Check load, impact, environment and machining cost. |
| Thermal conductivity + electrical insulation | Aluminum Nitride | Combines thermal-management function with electrical insulation. | Confirm thermal target, flatness, surface and assembly. |
| High-temperature strength + thermal shock | Silicon Nitride | Strong candidate for cyclic thermal and mechanical loading. | Check load case, temperature cycle and contact condition. |
| Machinability + high-temperature electrical insulation | Boron Nitride | Useful for machined insulating parts and specialized high-temperature applications. | Confirm grade, atmosphere and mechanical load. |

Common Material Selection Mistakes
Choosing by hardness alone
Hardness does not describe fracture behavior, thermal response or assembly risk.
Comparing generic material names
The same ceramic family can contain multiple grades with different properties.
Over-specifying tolerance
Precision grinding should follow functional needs, not habit.
Ignoring assembly conditions
Metal interfaces, press fits and thermal expansion can change the real failure risk.
