Aurum PD450 vs Extem XH1015
Polymer · grade comparison
Aurum PD450 and Extem XH1015 are both polymer grades. Extem XH1015 is the stronger of the two: yield strength 115 MPa (16.7 ksi) against 90 MPa (13.1 ksi) for Aurum PD450, about 28% more; tensile strength follows at 115 MPa (16.7 ksi) vs 92 MPa (13.3 ksi). In exchange, Aurum PD450 is the more ductile: elongation 40% versus 30% for Extem XH1015. Extem XH1015 is stiffer (3.6 GPa vs 2.9 GPa) and Aurum PD450 conducts heat better (0.29 W/m·K vs 0.22 W/m·K). On the shop floor, Aurum PD450 machines more easily (65 vs 55 out of 100) and Aurum PD450 welds better (45 vs 35 out of 100).
Aurum PD450Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Extem XH1015Choose it when strength drives the design.
Aurum PD450 vs Extem XH1015: 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.
