MgO Ceramic vs TiO2 Ceramic C-310

Ceramic · grade comparison

MgO Ceramic and TiO2 Ceramic C-310 are both ceramic grades. MgO Ceramic is the stronger of the two: tensile strength 100 MPa (14.5 ksi) against 55 MPa (7.98 ksi) for TiO2 Ceramic C-310, about 82% more. TiO2 Ceramic C-310 is harder — 850 HV against 620 HV for MgO Ceramic — which matters for wear surfaces and threads. MgO Ceramic is lighter (3.55 g/cm³ vs 3.9 g/cm³ for TiO2 Ceramic C-310) and MgO Ceramic is stiffer (300 GPa vs 220 GPa). On the shop floor, MgO Ceramic machines more easily (poor vs not recommended) and MgO Ceramic sits in a lower cost tier (standard, $$) than TiO2 Ceramic C-310 (high, $$$$).
