HfO2 vs TiO2 Ceramic
Ceramic · grade comparison
HfO2 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is harder — 950 HV against 800 HV for HfO2 — which matters for wear surfaces and threads. TiO2 Ceramic is lighter (4.15 g/cm³ vs 9.5 g/cm³ for HfO2) and HfO2 runs hotter in service (2,200°C vs 1,100°C continuous).
HfO2Choose it when the part sees heat.
TiO2 CeramicChoose it when surface hardness matters, or when weight is the constraint.
HfO2 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.

HfO2 vs TiO2 Ceramic — frequently asked
What is the difference between HfO2 and TiO2 Ceramic?
HfO2 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is harder — 950 HV against 800 HV for HfO2 — which matters for wear surfaces and threads. TiO2 Ceramic is lighter (4.15 g/cm³ vs 9.5 g/cm³ for HfO2) and HfO2 runs hotter in service (2,200°C vs 1,100°C continuous).
Which is cheaper, HfO2 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 HfO2 over TiO2 Ceramic?
Pick HfO2 when the part sees heat. Pick TiO2 Ceramic when surface hardness matters, or when weight is the constraint.
