MgO Ceramic vs MgTiO3
Ceramic · grade comparison
MgO Ceramic and MgTiO3 are both ceramic grades. MgO Ceramic is the stronger of the two: tensile strength 100 MPa (14.5 ksi) against 70 MPa (10.2 ksi) for MgTiO3, about 43% more. MgTiO3 is harder — 700 HV against 620 HV for MgO Ceramic — which matters for wear surfaces and threads. MgO Ceramic is lighter (3.55 g/cm³ vs 3.8 g/cm³ for MgTiO3) and MgO Ceramic is stiffer (300 GPa vs 150 GPa). On the shop floor, MgO Ceramic machines more easily (poor vs not recommended) and MgO Ceramic sits in a lower cost tier (standard, $$) than MgTiO3 (high, $$$$).
MgO CeramicChoose it when strength drives the design, or when weight is the constraint.
MgTiO3Choose it when surface hardness matters.
MgO Ceramic vs MgTiO3: 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 MgTiO3 — frequently asked
Is MgO Ceramic stronger than MgTiO3?
Yes. MgO Ceramic has a typical tensile strength of 100 MPa (14.5 ksi) against 70 MPa (10.2 ksi) for MgTiO3 — about 43% more.
Which is cheaper, MgO Ceramic or MgTiO3?
MgO Ceramic is the lower-cost material: it sits in the standard tier ($$) while MgTiO3 is high ($$$$). 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 MgTiO3?
MgO Ceramic. Its machinability rates poor (22/100) against not recommended (5/100) for MgTiO3.
