SrTiO3 vs TiO2 Ceramic
Ceramic · grade comparison
SrTiO3 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is harder — 950 HV against 690 HV for SrTiO3 — which matters for wear surfaces and threads. TiO2 Ceramic is lighter (4.15 g/cm³ vs 5.12 g/cm³ for SrTiO3) and SrTiO3 is stiffer (267 GPa vs 250 GPa).
SrTiO3Choose it when the part sees heat.
TiO2 CeramicChoose it when surface hardness matters, or when weight is the constraint.
SrTiO3 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.

SrTiO3 vs TiO2 Ceramic — frequently asked
What is the difference between SrTiO3 and TiO2 Ceramic?
SrTiO3 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is harder — 950 HV against 690 HV for SrTiO3 — which matters for wear surfaces and threads. TiO2 Ceramic is lighter (4.15 g/cm³ vs 5.12 g/cm³ for SrTiO3) and SrTiO3 is stiffer (267 GPa vs 250 GPa).
Which is cheaper, SrTiO3 or TiO2 Ceramic?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose SrTiO3 over TiO2 Ceramic?
Pick SrTiO3 when the part sees heat. Pick TiO2 Ceramic when surface hardness matters, or when weight is the constraint.
