Al2TiO5 vs TiO2 Ceramic
Ceramic · grade comparison
Al2TiO5 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is the stronger of the two: tensile strength 80 MPa (11.6 ksi) against 15 MPa (2.18 ksi) for Al2TiO5, about 5.3 times as much. TiO2 Ceramic is harder — 950 HV against 450 HV for Al2TiO5 — which matters for wear surfaces and threads. Al2TiO5 is lighter (3.2 g/cm³ vs 4.15 g/cm³ for TiO2 Ceramic) and TiO2 Ceramic is stiffer (250 GPa vs 15 GPa). On the shop floor, Al2TiO5 machines more easily (poor vs not recommended).
Al2TiO5Choose it when weight is the constraint, or when the part sees heat.
TiO2 CeramicChoose it when strength drives the design, or when surface hardness matters.
Al2TiO5 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.

Al2TiO5 vs TiO2 Ceramic — frequently asked
Is TiO2 Ceramic stronger than Al2TiO5?
Yes. TiO2 Ceramic has a typical tensile strength of 80 MPa (11.6 ksi) against 15 MPa (2.18 ksi) for Al2TiO5 — about 5.3 times as much.
Which is cheaper, Al2TiO5 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.
Which is easier to machine, Al2TiO5 or TiO2 Ceramic?
Al2TiO5. Its machinability rates poor (25/100) against not recommended (5/100) for TiO2 Ceramic.
