Cork vs Particleboard
Natural Material · grade comparison
Cork and Particleboard are both natural material grades. Particleboard is the stronger of the two: tensile strength 9 MPa (1.31 ksi) against 1 MPa (0.16 ksi) for Cork, about 8.2 times as much. In exchange, Cork is the more ductile: elongation 7% versus 0.6% for Particleboard. Cork is lighter (0.16 g/cm³ vs 0.68 g/cm³ for Particleboard) and Particleboard is stiffer (2.4 GPa vs 0.02 GPa). On the shop floor, Cork machines more easily (very good vs good) and Particleboard sits in a lower cost tier (budget, $) than Cork (premium, $$$).
CorkChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
ParticleboardChoose it when strength drives the design, or when cost is the deciding factor.
Cork vs Particleboard: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all natural material 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.

Cork vs Particleboard — frequently asked
Is Particleboard stronger than Cork?
Yes. Particleboard has a typical tensile strength of 9 MPa (1.31 ksi) against 1 MPa (0.16 ksi) for Cork — about 8.2 times as much.
Which is cheaper, Cork or Particleboard?
Particleboard is the lower-cost material: it sits in the budget tier ($) while Cork 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, Cork or Particleboard?
Cork. Its machinability rates very good (80/100) against good (65/100) for Particleboard.
