American yellow birch (Betula alleghaniensis)
Other names: none
Eastern USA, principally Northern and Lake States.
Yellow birch has a white sapwood and light reddish brown heartwood. The wood is generally straight grained with a fine uniform texture.
The wood works fairly easily, glues well with care, takes stain and polish extremely well, and nails and screws satisfactorily where pre-boring is advised. It dries rather slowly with little degrade, but it has moderately high shrinkage, so is susceptible to movement in performance.
The wood of yellow birch is heavy, hard and strong. It has very good wood bending properties, with good crushing strength and shock resistance.
Specific Gravity: 0.62 (12% M.C.)
Average Weight: 689 kg/m3 (12% M.C.)
Average Volumetric Shrinkage: 13.4% (Green to 6% M.C.)
Modulus of Elasticity: 13,859 MPa
Hardness: 5604 N
Non-resistant to heartwood decay. Liable to attack by common furniture beetle. Moderately resistant to preservative treatment but sapwood is permeable.
USA: Reasonable availability, but more limited if selected for colour, ie red birch (heartwood) or white birch (sapwood).
Export: Limited due to low demand, but increasing.
