Aurum PD450 GF30 vs Aurum PD450 LUB
Polymer · Aurum PD450 grade comparison
Aurum PD450 GF30 and Aurum PD450 LUB are two grades of the same polymer grade, Aurum PD450: GF30 (30% glass-fiber reinforced) versus LUB (bearing / lubricated grade). The chemistry is identical, so every difference below comes from the condition. Aurum PD450 GF30 is the stronger of the two: tensile strength 165 MPa (23.9 ksi) against 70 MPa (10.2 ksi) for Aurum PD450 LUB, about 136% more. In exchange, Aurum PD450 LUB is the more ductile: elongation 5% versus 2.5% for Aurum PD450 GF30. Aurum PD450 LUB is lighter (1.47 g/cm³ vs 1.55 g/cm³ for Aurum PD450 GF30) and Aurum PD450 GF30 is stiffer (9.5 GPa vs 2.9 GPa). On the shop floor, Aurum PD450 LUB machines more easily (very good vs fair).

Aurum PD450 LUBChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Aurum PD450 GF30 vs Aurum PD450 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.
