PA10T vs PA66
Polymer · grade comparison
PA10T and PA66 are both polymer grades. PA10T is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 80 MPa (11.6 ksi) for PA66, about 13% more; tensile strength follows at 95 MPa (13.8 ksi) vs 82 MPa (11.9 ksi). In exchange, PA66 is the more ductile: elongation 40% versus 25% for PA10T. PA66 is stiffer (3 GPa vs 2.8 GPa) and PA10T runs hotter in service (140°C vs 100°C continuous). On the shop floor, PA66 welds better (very good vs good) and PA66 sits in a lower cost tier (standard, $$) than PA10T (premium, $$$).
PA10TChoose it when strength drives the design, or when the part sees heat.
PA66Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
PA10T vs PA66: 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.

PA10T vs PA66 — frequently asked
Is PA10T stronger than PA66?
Yes. PA10T has a typical yield strength of 90 MPa (13.1 ksi) against 80 MPa (11.6 ksi) for PA66 — about 13% more. Tensile strength is 95 MPa (13.8 ksi) vs 82 MPa (11.9 ksi).
Which is cheaper, PA10T or PA66?
PA66 is the lower-cost material: it sits in the standard tier ($$) while PA10T is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, PA10T or PA66?
PA66, by a small margin. Both rate good for machinability — 65/100 against 60/100 for PA10T; for welding the order is PA66 first (very good, 70/100) then PA10T (good, 55/100).
