Ceran vs Mycalex
Glass · grade comparison
Ceran and Mycalex are both glass grades. Mycalex is the stronger of the two: tensile strength 45 MPa (6.53 ksi) against 30 MPa (4.35 ksi) for Ceran, about 50% more. Ceran is harder — 640 HV against 250 HV for Mycalex — which matters for wear surfaces and threads. Ceran is lighter (2.55 g/cm³ vs 3.4 g/cm³ for Mycalex) and Ceran is stiffer (92 GPa vs 65 GPa). On the shop floor, Mycalex machines more easily (very good vs not recommended).
CeranChoose it when surface hardness matters, or when weight is the constraint.
MycalexChoose it when strength drives the design, or when the part is machined in volume.
Ceran vs Mycalex: 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 Mycalex — frequently asked
Is Mycalex stronger than Ceran?
Yes. Mycalex has a typical tensile strength of 45 MPa (6.53 ksi) against 30 MPa (4.35 ksi) for Ceran — about 50% more.
Which is cheaper, Ceran or Mycalex?
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.
Which is easier to machine, Ceran or Mycalex?
Mycalex. Its machinability rates very good (75/100) against not recommended (12/100) for Ceran.
