BeO vs MgTiO3
Ceramic · grade comparison
BeO and MgTiO3 are both ceramic grades. BeO is the stronger of the two: tensile strength 130 MPa (18.9 ksi) against 70 MPa (10.2 ksi) for MgTiO3, about 86% more. BeO is harder — 1,200 HV against 700 HV for MgTiO3 — which matters for wear surfaces and threads. BeO is lighter (2.87 g/cm³ vs 3.8 g/cm³ for MgTiO3) and BeO is stiffer (345 GPa vs 150 GPa).
BeOChoose it when strength drives the design, or when surface hardness matters.
BeO 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.

BeO vs MgTiO3 — frequently asked
Is BeO stronger than MgTiO3?
Yes. BeO has a typical tensile strength of 130 MPa (18.9 ksi) against 70 MPa (10.2 ksi) for MgTiO3 — about 86% more.
Which is cheaper, BeO or MgTiO3?
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 BeO over MgTiO3?
Pick BeO when strength drives the design, or when surface hardness matters.
