Cork Composition (Cork-Rubber) vs Rawhide
Natural Material · grade comparison
Cork Composition (Cork-Rubber) and Rawhide are both natural material grades. Rawhide is the stronger of the two: tensile strength 70 MPa (10.2 ksi) against 2 MPa (0.305 ksi) for Cork Composition (Cork-Rubber), about 33 times as much. Cork Composition (Cork-Rubber) is lighter (0.75 g/cm³ vs 1.05 g/cm³ for Rawhide) and Rawhide is stiffer (1.2 GPa vs 0.03 GPa). On the shop floor, Cork Composition (Cork-Rubber) machines more easily (excellent vs fair).

RawhideChoose it when strength drives the design.
Cork Composition (Cork-Rubber) vs Rawhide: 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.
