PA11 vs PA6T
Polymer · grade comparison
PA11 and PA6T are both polymer grades. PA6T is the stronger of the two: yield strength 95 MPa (13.8 ksi) against 40 MPa (5.8 ksi) for PA11, about 138% more; tensile strength follows at 100 MPa (14.5 ksi) vs 48 MPa (6.96 ksi). In exchange, PA11 is the more ductile: elongation 45% versus 20% for PA6T, and PA6T is harder (86 Shore D vs 75 Shore D). PA11 is lighter (1.03 g/cm³ vs 1.19 g/cm³ for PA6T) and PA6T is stiffer (3.2 GPa vs 1.6 GPa). On the shop floor, PA11 welds better (very good vs good).
PA11Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PA6TChoose it when strength drives the design, or when the part sees heat.
PA11 vs PA6T: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer 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.

PA11 vs PA6T — frequently asked
Is PA6T stronger than PA11?
Yes. PA6T has a typical yield strength of 95 MPa (13.8 ksi) against 40 MPa (5.8 ksi) for PA11 — about 138% more. Tensile strength is 100 MPa (14.5 ksi) vs 48 MPa (6.96 ksi).
Which is cheaper, PA11 or PA6T?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, PA11 or PA6T?
PA11, by a small margin. Both rate good for machinability — 65/100 against 60/100 for PA6T; for welding the order is PA11 first (very good, 70/100) then PA6T (good, 60/100).
