YG8 vs YN05
Ceramic · grade comparison
YG8 and YN05 are both ceramic grades. YN05 is harder — 1,800 HV against 1,350 HV for YG8 — which matters for wear surfaces and threads. YN05 is lighter (5.9 g/cm³ vs 14.7 g/cm³ for YG8) and YG8 is stiffer (600 GPa vs 400 GPa).
YN05Choose it when surface hardness matters, or when weight is the constraint.
YG8 vs YN05: 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.

YG8 vs YN05 — frequently asked
What is the difference between YG8 and YN05?
YG8 and YN05 are both ceramic grades. YN05 is harder — 1,800 HV against 1,350 HV for YG8 — which matters for wear surfaces and threads. YN05 is lighter (5.9 g/cm³ vs 14.7 g/cm³ for YG8) and YG8 is stiffer (600 GPa vs 400 GPa).
Which is cheaper, YG8 or YN05?
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 YG8 over YN05?
Pick YN05 when surface hardness matters, or when weight is the constraint.
