C1 vs YG6
Ceramic · grade comparison
C1 and YG6 are both ceramic grades. YG6 is the more ductile: elongation 0.2% versus 0% for C1, and YG6 is harder (1,580 HV vs 1,480 HV). YG6 runs hotter in service (600°C vs 550°C continuous).
YG6Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C1 vs YG6: 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.

C1 vs YG6 — frequently asked
What is the difference between C1 and YG6?
C1 and YG6 are both ceramic grades. YG6 is the more ductile: elongation 0.2% versus 0% for C1, and YG6 is harder (1,580 HV vs 1,480 HV). YG6 runs hotter in service (600°C vs 550°C continuous).
Which is cheaper, C1 or YG6?
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 C1 over YG6?
Pick YG6 when the part is bent, formed or impact-loaded, or when the part sees heat.
