MgO Ceramic vs TiO2 Ceramic
Ceramic · grade comparison
MgO Ceramic and TiO2 Ceramic are both ceramic grades. MgO Ceramic is the stronger of the two: tensile strength 100 MPa (14.5 ksi) against 80 MPa (11.6 ksi) for TiO2 Ceramic, about 25% more. TiO2 Ceramic is harder — 950 HV against 620 HV for MgO Ceramic — which matters for wear surfaces and threads. MgO Ceramic is lighter (3.55 g/cm³ vs 4.15 g/cm³ for TiO2 Ceramic) and MgO Ceramic is stiffer (300 GPa vs 250 GPa). On the shop floor, MgO Ceramic machines more easily (poor vs not recommended) and MgO Ceramic sits in a lower cost tier (standard, $$) than TiO2 Ceramic (high, $$$$).
MgO CeramicChoose it when strength drives the design, or when weight is the constraint.
TiO2 CeramicChoose it when surface hardness matters.
MgO Ceramic 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.

MgO Ceramic vs TiO2 Ceramic — frequently asked
Is MgO Ceramic stronger than TiO2 Ceramic?
Yes. MgO Ceramic has a typical tensile strength of 100 MPa (14.5 ksi) against 80 MPa (11.6 ksi) for TiO2 Ceramic — about 25% more.
Which is cheaper, MgO Ceramic or TiO2 Ceramic?
MgO Ceramic is the lower-cost material: it sits in the standard 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.
Which is easier to machine, MgO Ceramic or TiO2 Ceramic?
MgO Ceramic. Its machinability rates poor (22/100) against not recommended (5/100) for TiO2 Ceramic.
