MgO Ceramic vs MnZn Ferrite
Ceramic · grade comparison
MgO Ceramic and MnZn Ferrite are both ceramic grades. MgO Ceramic is the stronger of the two: tensile strength 100 MPa (14.5 ksi) against 30 MPa (4.35 ksi) for MnZn Ferrite, about 3.3 times as much. MgO Ceramic is lighter (3.55 g/cm³ vs 4.85 g/cm³ for MnZn Ferrite) and MgO Ceramic is stiffer (300 GPa vs 150 GPa). On the shop floor, MgO Ceramic sits in a lower cost tier (standard, $$) than MnZn Ferrite (premium, $$$).

MgO Ceramic vs MnZn Ferrite: 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 MnZn Ferrite — frequently asked
Is MgO Ceramic stronger than MnZn Ferrite?
Yes. MgO Ceramic has a typical tensile strength of 100 MPa (14.5 ksi) against 30 MPa (4.35 ksi) for MnZn Ferrite — about 3.3 times as much.
Which is cheaper, MgO Ceramic or MnZn Ferrite?
MgO Ceramic is the lower-cost material: it sits in the standard tier ($$) while MnZn Ferrite is premium ($$$). 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 MnZn Ferrite?
MgO Ceramic, by a small margin. Both rate poor for machinability — 22/100 against 15/100 for MnZn Ferrite.
