TT7K12 vs YG6
Ceramic · grade comparison
TT7K12 and YG6 are both ceramic grades. YG6 is harder — 1,580 HV against 1,200 HV for TT7K12 — which matters for wear surfaces and threads. TT7K12 is lighter (13.15 g/cm³ vs 14.9 g/cm³ for YG6) and YG6 is stiffer (630 GPa vs 520 GPa).
TT7K12Choose it when weight is the constraint, or when the part sees heat.
YG6Choose it when surface hardness matters.
TT7K12 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.

TT7K12 vs YG6 — frequently asked
What is the difference between TT7K12 and YG6?
TT7K12 and YG6 are both ceramic grades. YG6 is harder — 1,580 HV against 1,200 HV for TT7K12 — which matters for wear surfaces and threads. TT7K12 is lighter (13.15 g/cm³ vs 14.9 g/cm³ for YG6) and YG6 is stiffer (630 GPa vs 520 GPa).
Which is cheaper, TT7K12 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 TT7K12 over YG6?
Pick TT7K12 when weight is the constraint, or when the part sees heat. Pick YG6 when surface hardness matters.
