PA610 GF30 vs PA610 LUB
Polymer · PA610 grade comparison
PA610 GF30 and PA610 LUB are two grades of the same polymer grade, PA610: GF30 (30–33 % glass-fiber reinforced) versus LUB (internally lubricated bearing grade). The chemistry is identical, so every difference below comes from the condition. PA610 GF30 is the stronger of the two: yield strength 58 MPa (8.41 ksi) against 54 MPa (7.83 ksi) for PA610 LUB, about 7% more; tensile strength follows at 140 MPa (20.3 ksi) vs 55 MPa (7.98 ksi). In exchange, PA610 LUB is the more ductile: elongation 40% versus 3% for PA610 GF30. PA610 LUB is lighter (1.12 g/cm³ vs 1.31 g/cm³ for PA610 GF30) and PA610 GF30 is stiffer (7.5 GPa vs 2.2 GPa). On the shop floor, PA610 LUB machines more easily (very good vs fair) and PA610 GF30 welds better (good vs fair).
PA610 GF30Choose it when strength drives the design, or when the part sees heat.
PA610 LUBChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PA610 GF30 vs PA610 LUB: 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.

PA610 GF30 vs PA610 LUB — frequently asked
Is PA610 GF30 stronger than PA610 LUB?
Yes. PA610 GF30 has a typical yield strength of 58 MPa (8.41 ksi) against 54 MPa (7.83 ksi) for PA610 LUB — about 7% more. Tensile strength is 140 MPa (20.3 ksi) vs 55 MPa (7.98 ksi).
Which grade does FabDigit quote by default, GF30 or LUB?
UF-DAM is the default PA610 condition in the FabDigit quote flow (neither GF30 nor LUB). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, PA610 GF30 or PA610 LUB?
PA610 LUB. Its machinability rates very good (82/100) against fair (50/100) for PA610 GF30; for welding the order is PA610 GF30 first (good, 55/100) then PA610 LUB (fair, 40/100).
