Neoceram vs ZERODUR
Glass · grade comparison
Neoceram and ZERODUR 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 ZERODUR, about 67% more. Neoceram is harder — 700 HV against 620 HV for ZERODUR — which matters for wear surfaces and threads. Neoceram runs hotter in service (700°C vs 500°C continuous) and Neoceram conducts heat better (1.7 W/m·K vs 1.5 W/m·K). On the shop floor, ZERODUR machines more easily (poor vs not recommended) and ZERODUR sits in a lower cost tier (standard, $$) than Neoceram (high, $$$$).
NeoceramChoose it when strength drives the design, or when surface hardness matters.
ZERODURChoose it when the part is machined in volume, or when cost is the deciding factor.
Neoceram vs ZERODUR: 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.

Neoceram vs ZERODUR — frequently asked
Is Neoceram stronger than ZERODUR?
Yes. Neoceram has a typical tensile strength of 50 MPa (7.25 ksi) against 30 MPa (4.35 ksi) for ZERODUR — about 67% more.
Which is cheaper, Neoceram or ZERODUR?
ZERODUR is the lower-cost material: it sits in the standard tier ($$) while Neoceram is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, Neoceram or ZERODUR?
ZERODUR. Its machinability rates poor (20/100) against not recommended (8/100) for Neoceram.
