Maple vs Walnut
Natural Material · grade comparison
Maple and Walnut are both natural material grades. Maple is the more ductile: elongation 1.5% versus 1.2% for Walnut. Walnut is lighter (0.61 g/cm³ vs 0.71 g/cm³ for Maple) and Maple is stiffer (12.6 GPa vs 11.6 GPa). On the shop floor, Walnut machines more easily (excellent vs good).
MapleChoose it when the part is bent, formed or impact-loaded.
WalnutChoose it when weight is the constraint, or when the part is machined in volume.
Maple 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.

Maple vs Walnut — frequently asked
What is the difference between Maple and Walnut?
Maple and Walnut are both natural material grades. Maple is the more ductile: elongation 1.5% versus 1.2% for Walnut. Walnut is lighter (0.61 g/cm³ vs 0.71 g/cm³ for Maple) and Maple is stiffer (12.6 GPa vs 11.6 GPa).
Which is cheaper, Maple or Walnut?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Maple or Walnut?
Walnut. Its machinability rates excellent (88/100) against good (68/100) for Maple.
