C2 vs YG8
Ceramic · grade comparison
C2 and YG8 are both ceramic grades. YG8 is the more ductile: elongation 0.1% versus 0% for C2, and C2 is harder (1,580 HV vs 1,350 HV). C2 conducts heat better (85 W/m·K vs 75 W/m·K).
YG8Choose it when the part is bent, formed or impact-loaded.
C2 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.

C2 vs YG8 — frequently asked
What is the difference between C2 and YG8?
C2 and YG8 are both ceramic grades. YG8 is the more ductile: elongation 0.1% versus 0% for C2, and C2 is harder (1,580 HV vs 1,350 HV). C2 conducts heat better (85 W/m·K vs 75 W/m·K).
Which is cheaper, C2 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 C2 over YG8?
Pick YG8 when the part is bent, formed or impact-loaded.
