N-F2 vs N-SF11
Glass · grade comparison
N-F2 and N-SF11 are both glass grades. N-F2 is lighter (2.65 g/cm³ vs 3.2 g/cm³ for N-SF11) and N-SF11 is stiffer (92 GPa vs 57 GPa).

N-F2 vs N-SF11: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all glass 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.

N-F2 vs N-SF11 — frequently asked
What is the difference between N-F2 and N-SF11?
N-F2 and N-SF11 are both glass grades. N-F2 is lighter (2.65 g/cm³ vs 3.2 g/cm³ for N-SF11) and N-SF11 is stiffer (92 GPa vs 57 GPa).
Which is cheaper, N-F2 or N-SF11?
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.
Which is easier to machine, N-F2 or N-SF11?
N-F2, by a small margin. Both rate poor for machinability — 22/100 against 15/100 for N-SF11.
