T15K6 vs YG6
Ceramic · grade comparison
T15K6 and YG6 are both ceramic grades. YG6 is the stronger of the two: tensile strength 1,100 MPa (160 ksi) against 800 MPa (116 ksi) for T15K6, about 38% more. YG6 is the more ductile: elongation 0.2% versus 0.1% for T15K6. T15K6 is lighter (11.4 g/cm³ vs 14.9 g/cm³ for YG6) and YG6 is stiffer (630 GPa vs 520 GPa).
T15K6Choose it when weight is the constraint, or when the part sees heat.
YG6Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
T15K6 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.

T15K6 vs YG6 — frequently asked
Is YG6 stronger than T15K6?
Yes. YG6 has a typical tensile strength of 1,100 MPa (160 ksi) against 800 MPa (116 ksi) for T15K6 — about 38% more.
Which is cheaper, T15K6 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 T15K6 over YG6?
Pick T15K6 when weight is the constraint, or when the part sees heat. Pick YG6 when strength drives the design, or when the part is bent, formed or impact-loaded.
