MnZn Ferrite vs Spinel
Ceramic · grade comparison
MnZn Ferrite and Spinel are both ceramic grades. Spinel is the stronger of the two: tensile strength 120 MPa (17.4 ksi) against 30 MPa (4.35 ksi) for MnZn Ferrite, about 4.0 times as much. Spinel is harder — 1,350 HV against 600 HV for MnZn Ferrite — which matters for wear surfaces and threads. Spinel is lighter (3.55 g/cm³ vs 4.85 g/cm³ for MnZn Ferrite) and Spinel is stiffer (265 GPa vs 150 GPa). On the shop floor, MnZn Ferrite machines more easily (poor vs not recommended) and MnZn Ferrite sits in a lower cost tier (premium, $$$) than Spinel (high, $$$$).
MnZn FerriteChoose it when the part is machined in volume, or when cost is the deciding factor.
SpinelChoose it when strength drives the design, or when surface hardness matters.
MnZn Ferrite vs Spinel: 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.

MnZn Ferrite vs Spinel — frequently asked
Is Spinel stronger than MnZn Ferrite?
Yes. Spinel has a typical tensile strength of 120 MPa (17.4 ksi) against 30 MPa (4.35 ksi) for MnZn Ferrite — about 4.0 times as much.
Which is cheaper, MnZn Ferrite or Spinel?
MnZn Ferrite is the lower-cost material: it sits in the premium tier ($$$) while Spinel is high ($$$$). 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, MnZn Ferrite or Spinel?
MnZn Ferrite. Its machinability rates poor (15/100) against not recommended (5/100) for Spinel.
