CeO2 vs TiO2 Ceramic
Ceramic · grade comparison
CeO2 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is harder — 950 HV against 600 HV for CeO2 — which matters for wear surfaces and threads. TiO2 Ceramic is lighter (4.15 g/cm³ vs 7.15 g/cm³ for CeO2) and TiO2 Ceramic is stiffer (250 GPa vs 180 GPa). On the shop floor, CeO2 sits in a lower cost tier (premium, $$$) than TiO2 Ceramic (high, $$$$).
CeO2Choose it when the part sees heat, or when cost is the deciding factor.
TiO2 CeramicChoose it when surface hardness matters, or when weight is the constraint.
CeO2 vs TiO2 Ceramic: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all ceramic grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

CeO2 vs TiO2 Ceramic — frequently asked
What is the difference between CeO2 and TiO2 Ceramic?
CeO2 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is harder — 950 HV against 600 HV for CeO2 — which matters for wear surfaces and threads. TiO2 Ceramic is lighter (4.15 g/cm³ vs 7.15 g/cm³ for CeO2) and TiO2 Ceramic is stiffer (250 GPa vs 180 GPa).
Which is cheaper, CeO2 or TiO2 Ceramic?
CeO2 is the lower-cost material: it sits in the premium tier ($$$) while TiO2 Ceramic is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose CeO2 over TiO2 Ceramic?
Pick CeO2 when the part sees heat, or when cost is the deciding factor. Pick TiO2 Ceramic when surface hardness matters, or when weight is the constraint.
