YG3 vs YW1
Ceramic · grade comparison
YG3 and YW1 are both ceramic grades. YG3 is the stronger of the two: tensile strength 1,100 MPa (160 ksi) against 850 MPa (123 ksi) for YW1, about 29% more. YW1 is lighter (12.9 g/cm³ vs 15.1 g/cm³ for YG3) and YG3 is stiffer (650 GPa vs 520 GPa).
YG3Choose it when strength drives the design.
YW1Choose it when weight is the constraint, or when the part sees heat.
YG3 vs YW1: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all ceramic 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.

YG3 vs YW1 — frequently asked
Is YG3 stronger than YW1?
Yes. YG3 has a typical tensile strength of 1,100 MPa (160 ksi) against 850 MPa (123 ksi) for YW1 — about 29% more.
Which is cheaper, YG3 or YW1?
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 YG3 over YW1?
Pick YG3 when strength drives the design. Pick YW1 when weight is the constraint, or when the part sees heat.
