YG6X vs YG8
Ceramic · grade comparison
YG6X and YG8 are both ceramic grades. YG6X is harder — 1,750 HV against 1,350 HV for YG8 — which matters for wear surfaces and threads. YG6X runs hotter in service (800°C vs 600°C continuous).
YG6XChoose it when surface hardness matters, or when the part sees heat.
YG6X vs YG8: 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.

YG6X vs YG8 — frequently asked
What is the difference between YG6X and YG8?
YG6X and YG8 are both ceramic grades. YG6X is harder — 1,750 HV against 1,350 HV for YG8 — which matters for wear surfaces and threads. YG6X runs hotter in service (800°C vs 600°C continuous).
Which is cheaper, YG6X or YG8?
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 YG6X over YG8?
Pick YG6X when surface hardness matters, or when the part sees heat.
