Mycalex vs Pyroceram 9606
Glass · grade comparison
Mycalex and Pyroceram 9606 are both glass grades. Pyroceram 9606 is the stronger of the two: tensile strength 120 MPa (17.4 ksi) against 45 MPa (6.53 ksi) for Mycalex, about 167% more. In exchange, Mycalex is the more ductile: elongation 0.1% versus 0% for Pyroceram 9606, and Pyroceram 9606 is harder (700 HV vs 250 HV). Pyroceram 9606 is lighter (2.6 g/cm³ vs 3.4 g/cm³ for Mycalex) and Pyroceram 9606 is stiffer (120 GPa vs 65 GPa). On the shop floor, Mycalex machines more easily (very good vs not recommended).
MycalexChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Pyroceram 9606Choose it when strength drives the design, or when weight is the constraint.
Mycalex vs Pyroceram 9606: 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.

Mycalex vs Pyroceram 9606 — frequently asked
Is Pyroceram 9606 stronger than Mycalex?
Yes. Pyroceram 9606 has a typical tensile strength of 120 MPa (17.4 ksi) against 45 MPa (6.53 ksi) for Mycalex — about 167% more.
Which is cheaper, Mycalex or Pyroceram 9606?
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, Mycalex or Pyroceram 9606?
Mycalex. Its machinability rates very good (75/100) against not recommended (5/100) for Pyroceram 9606.
