MXD6 vs PA11

Polymer · grade comparison

MXD6 and PA11 are both polymer grades. MXD6 is the stronger of the two: tensile strength 200 MPa (29 ksi) against 48 MPa (6.96 ksi) for PA11, about 4.2 times as much. In exchange, PA11 is the more ductile: elongation 45% versus 2.5% for MXD6. PA11 is lighter (1.03 g/cm³ vs 1.48 g/cm³ for MXD6) and MXD6 is stiffer (10 GPa vs 1.6 GPa). On the shop floor, PA11 machines more easily (good vs fair), PA11 welds better (very good vs good), and MXD6 sits in a lower cost tier (standard, $$) than PA11 (premium, $$$).

MXD6Choose it when strength drives the design, or when the part sees heat.

PA11Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

MXD6 vs PA11 — frequently asked

Is MXD6 stronger than PA11?

Yes. MXD6 has a typical tensile strength of 200 MPa (29 ksi) against 48 MPa (6.96 ksi) for PA11 — about 4.2 times as much.

Which is cheaper, MXD6 or PA11?

MXD6 is the lower-cost material: it sits in the standard tier ($$) while PA11 is premium ($$$). 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, MXD6 or PA11?

PA11. Its machinability rates good (65/100) against fair (40/100) for MXD6; for welding the order is PA11 first (very good, 70/100) then MXD6 (good, 55/100).
