PA66 vs Vero

Polymer · grade comparison

PA66 and Vero are both polymer grades, both engineering plastic. PA66 is the stronger of the two: tensile strength 82 MPa (11.9 ksi) against 57 MPa (8.27 ksi) for Vero, about 44% more. PA66 is the more ductile: elongation 40% versus 17% for Vero. PA66 is stiffer (3 GPa vs 2.5 GPa) and PA66 runs hotter in service (100°C vs 45°C continuous). On the shop floor, PA66 machines more easily (65 vs 55 out of 100), PA66 welds better (very good vs not recommended), and PA66 sits in a lower cost tier (standard, $$) than Vero (specialty, $$$$$).

PA66Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

PA66 vs Vero — frequently asked

Is PA66 stronger than Vero?

Yes. PA66 has a typical tensile strength of 82 MPa (11.9 ksi) against 57 MPa (8.27 ksi) for Vero — about 44% more.

Which is cheaper, PA66 or Vero?

PA66 is the lower-cost material: it sits in the standard tier ($$) while Vero is specialty ($$$$$). 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, PA66 or Vero?

PA66, by a small margin. Both rate good for machinability — 65/100 against 55/100 for Vero; for welding the order is PA66 first (very good, 70/100) then Vero (not recommended, 5/100).
