BeO Ceramic vs MgTiO3

Ceramic · grade comparison

BeO Ceramic and MgTiO3 are both ceramic grades. BeO Ceramic is the stronger of the two: tensile strength 140 MPa (20.3 ksi) against 70 MPa (10.2 ksi) for MgTiO3, about 100% more. BeO Ceramic is harder — 1,200 HV against 700 HV for MgTiO3 — which matters for wear surfaces and threads. BeO Ceramic is lighter (2.87 g/cm³ vs 3.8 g/cm³ for MgTiO3) and BeO Ceramic is stiffer (345 GPa vs 150 GPa).

BeO Ceramic vs MgTiO3 — frequently asked

Is BeO Ceramic stronger than MgTiO3?

Yes. BeO Ceramic has a typical tensile strength of 140 MPa (20.3 ksi) against 70 MPa (10.2 ksi) for MgTiO3 — about 100% more.

Which is cheaper, BeO Ceramic 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 Ceramic over MgTiO3?

Pick BeO Ceramic when strength drives the design, or when surface hardness matters.
