Ceran vs Pyroceram 9606 — frequently asked

Is Pyroceram 9606 stronger than Ceran?

Yes. Pyroceram 9606 has a typical tensile strength of 120 MPa (17.4 ksi) against 30 MPa (4.35 ksi) for Ceran — about 4.0 times as much.

Which is cheaper, Ceran 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, Ceran or Pyroceram 9606?

Ceran, by a small margin. Both rate not recommended for machinability — 12/100 against 5/100 for Pyroceram 9606.
