YG6 A vs YG6 C
Ceramic · YG6 temper comparison
YG6 A and YG6 C are two conditions of the same ceramic grade, YG6: A (solution annealed) versus C (YG6C). The chemistry is identical, so every difference below comes from the condition. YG6 C is the stronger of the two: tensile strength 1,200 MPa (174 ksi) against 1,000 MPa (145 ksi) for YG6 A, about 20% more. YG6 C is the more ductile: elongation 0.25% versus 0.15% for YG6 A, and YG6 A is harder (1,820 HV vs 1,400 HV). YG6 A runs hotter in service (700°C vs 600°C continuous) and YG6 C conducts heat better (90 W/m·K vs 70 W/m·K).
YG6 AChoose it when the part sees heat.
YG6 CChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
YG6 A vs YG6 C: 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 A vs YG6 C — frequently asked
Is YG6 C stronger than YG6 A?
Yes. YG6 C has a typical tensile strength of 1,200 MPa (174 ksi) against 1,000 MPa (145 ksi) for YG6 A — about 20% more.
Which condition does FabDigit quote by default, A or C?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
When should I choose YG6 A over YG6 C?
Pick YG6 A when the part sees heat. Pick YG6 C when strength drives the design, or when the part is bent, formed or impact-loaded.
