Beech vs Birch
Natural Material · grade comparison
Beech and Birch are both natural material grades. Birch is the more ductile: elongation 1.5% versus 1.2% for Beech. Birch is lighter (0.65 g/cm³ vs 0.72 g/cm³ for Beech).
BirchChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Beech vs Birch: 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 Birch — frequently asked
What is the difference between Beech and Birch?
Beech and Birch are both natural material grades. Birch is the more ductile: elongation 1.5% versus 1.2% for Beech. Birch is lighter (0.65 g/cm³ vs 0.72 g/cm³ for Beech).
Which is cheaper, Beech or Birch?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Beech or Birch?
Birch, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for Beech.
