Aurum PD450 CF30 vs Aurum PD450 LUB

Polymer · Aurum PD450 grade comparison

Aurum PD450 CF30 and Aurum PD450 LUB are two grades of the same polymer grade, Aurum PD450: CF30 (30% carbon-fiber reinforced) versus LUB (bearing / lubricated grade). The chemistry is identical, so every difference below comes from the condition. Aurum PD450 CF30 is the stronger of the two: tensile strength 205 MPa (29.7 ksi) against 70 MPa (10.2 ksi) for Aurum PD450 LUB, about 193% more. In exchange, Aurum PD450 LUB is the more ductile: elongation 5% versus 1.8% for Aurum PD450 CF30. Aurum PD450 CF30 is stiffer (18 GPa vs 2.9 GPa) and Aurum PD450 CF30 conducts heat better (0.8 W/m·K vs 0.5 W/m·K). On the shop floor, Aurum PD450 LUB machines more easily (very good vs fair).
