PA11 vs PA612
Polymer · grade comparison
PA11 and PA612 are both polymer grades. PA612 is the stronger of the two: yield strength 58 MPa (8.41 ksi) against 40 MPa (5.8 ksi) for PA11, about 45% more; tensile strength follows at 60 MPa (8.7 ksi) vs 48 MPa (6.96 ksi). PA612 is the more ductile: elongation 120% versus 45% for PA11, and PA612 is harder (79 Shore D vs 75 Shore D). PA11 is lighter (1.03 g/cm³ vs 1.07 g/cm³ for PA612) and PA612 is stiffer (2.1 GPa vs 1.6 GPa).
PA11Choose it when weight is the constraint.
PA612Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
PA11 vs PA612: 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 PA612 — frequently asked
Is PA612 stronger than PA11?
Yes. PA612 has a typical yield strength of 58 MPa (8.41 ksi) against 40 MPa (5.8 ksi) for PA11 — about 45% more. Tensile strength is 60 MPa (8.7 ksi) vs 48 MPa (6.96 ksi).
Which is cheaper, PA11 or PA612?
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 PA612?
PA612. Its machinability rates very good (72/100) against good (65/100) for PA11.
