YG6 vs YW2
Ceramic · grade comparison
YG6 and YW2 are both ceramic grades. YG6 is the stronger of the two: tensile strength 1,100 MPa (160 ksi) against 1,000 MPa (145 ksi) for YW2, about 10% more. YG6 is the more ductile: elongation 0.2% versus 0% for YW2, and YG6 is harder (1,580 HV vs 1,450 HV). YW2 is lighter (13 g/cm³ vs 14.9 g/cm³ for YG6) and YG6 is stiffer (630 GPa vs 540 GPa).
YG6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
YW2Choose it when weight is the constraint, or when the part sees heat.
YG6 vs YW2: 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.

YG6 vs YW2 — frequently asked
Is YG6 stronger than YW2?
Yes. YG6 has a typical tensile strength of 1,100 MPa (160 ksi) against 1,000 MPa (145 ksi) for YW2 — about 10% more.
Which is cheaper, YG6 or YW2?
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 YG6 over YW2?
Pick YG6 when strength drives the design, or when the part is bent, formed or impact-loaded. Pick YW2 when weight is the constraint, or when the part sees heat.
