PA6 vs PA610
Polymer · grade comparison
PA6 and PA610 are both polymer grades. PA6 is the stronger of the two: yield strength 75 MPa (10.9 ksi) against 58 MPa (8.41 ksi) for PA610, about 29% more; tensile strength follows at 80 MPa (11.6 ksi) vs 60 MPa (8.7 ksi). In exchange, PA610 is the more ductile: elongation 120% versus 60% for PA6. PA610 is lighter (1.08 g/cm³ vs 1.14 g/cm³ for PA6) and PA6 is stiffer (3 GPa vs 2.2 GPa). On the shop floor, PA6 sits in a lower cost tier (budget, $) than PA610 (premium, $$$).
PA6Choose it when strength drives the design, or when cost is the deciding factor.
PA610Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PA6 vs PA610: 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.
