Ceran vs Neoceram
Glass · grade comparison
Ceran and Neoceram are both glass grades. Neoceram is the stronger of the two: tensile strength 50 MPa (7.25 ksi) against 30 MPa (4.35 ksi) for Ceran, about 67% more. Neoceram is harder — 700 HV against 640 HV for Ceran — which matters for wear surfaces and threads.
NeoceramChoose it when strength drives the design, or when surface hardness matters.
Ceran vs Neoceram: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all glass 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.

Ceran vs Neoceram — frequently asked
Is Neoceram stronger than Ceran?
Yes. Neoceram has a typical tensile strength of 50 MPa (7.25 ksi) against 30 MPa (4.35 ksi) for Ceran — about 67% more.
Which is cheaper, Ceran or Neoceram?
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 Ceran over Neoceram?
Pick Neoceram when strength drives the design, or when surface hardness matters.
