Neoceram vs Pyroceram 9606 — frequently asked

Is Pyroceram 9606 stronger than Neoceram?

Yes. Pyroceram 9606 has a typical tensile strength of 120 MPa (17.4 ksi) against 50 MPa (7.25 ksi) for Neoceram — about 140% more.

Which is cheaper, Neoceram 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.

When should I choose Neoceram over Pyroceram 9606?

Pick Neoceram when weight is the constraint. Pick Pyroceram 9606 when strength drives the design, or when the part sees heat.
