Beech vs Walnut
Natural Material · grade comparison
Beech and Walnut are both natural material grades. Beech is the stronger of the two: tensile strength 110 MPa (16 ksi) against 100 MPa (14.5 ksi) for Walnut, about 10% more. Walnut is lighter (0.61 g/cm³ vs 0.72 g/cm³ for Beech) and Beech is stiffer (14 GPa vs 11.6 GPa). On the shop floor, Walnut machines more easily (excellent vs very good) and Beech sits in a lower cost tier (budget, $) than Walnut (standard, $$).
BeechChoose it when strength drives the design, or when the part sees heat.
WalnutChoose it when weight is the constraint, or when the part is machined in volume.
Beech vs Walnut: 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.

Beech vs Walnut — frequently asked
Is Beech stronger than Walnut?
Yes. Beech has a typical tensile strength of 110 MPa (16 ksi) against 100 MPa (14.5 ksi) for Walnut — about 10% more.
Which is cheaper, Beech or Walnut?
Beech is the lower-cost material: it sits in the budget tier ($) while Walnut is standard ($$). 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, Beech or Walnut?
Walnut. Its machinability rates excellent (88/100) against very good (70/100) for Beech.
