Agilus vs Durus
Polymer · grade comparison
Agilus and Durus are both polymer grades. Durus is the stronger of the two: tensile strength 25 MPa (3.63 ksi) against 3 MPa (0.406 ksi) for Agilus, about 8.9 times as much. In exchange, Agilus is the more ductile: elongation 245% versus 45% for Durus. Durus is stiffer (1.1 GPa vs 0 GPa) and Agilus runs hotter in service (50°C vs 45°C continuous). On the shop floor, Durus machines more easily (fair vs not recommended) and Durus sits in a lower cost tier (high, $$$$) than Agilus (specialty, $$$$$).
AgilusChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
DurusChoose it when strength drives the design, or when the part is machined in volume.
Agilus vs Durus: 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.

Agilus vs Durus — frequently asked
Is Durus stronger than Agilus?
Yes. Durus has a typical tensile strength of 25 MPa (3.63 ksi) against 3 MPa (0.406 ksi) for Agilus — about 8.9 times as much.
Which is cheaper, Agilus or Durus?
Durus is the lower-cost material: it sits in the high tier ($$$$) while Agilus is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, Agilus or Durus?
Durus. Its machinability rates fair (45/100) against not recommended (12/100) for Agilus.
