Modulus of Rupture: 13,600 lbf/in2 (93.8 MPa)
Elastic Modulus: 1,900,000 lbf/in2 (13.10 GPa)
Crushing Strength: 7,450 lbf/in2 (51.4 MPa)
Shrinkage: Radial: 6.5%, Tangential: 9.9%, Volumetric: 16.7%, T/R Ratio: 1.5
Color/Appearance: Heartwood tends to be a light reddish brown, with nearly white sapwood. Occasionally figured pieces are available with a wide, shallow curl similar to the curl found in Cherry. There is virtually no color distinction between annual growth rings, giving Birch a somewhat dull, uniform appearance.
Grain/Texture: Grain is generally straight or slightly wavy. Pores are closed, with a fine, even texture
Rot Resistance: Birch is perishable, and will readily rot and decay if exposed to the elements. The wood is also susceptible to insect attack.
Workability: Generally easy to work with hand and machine tools, though boards with wild grain can cause grain tearout during machining operations. Turns, glues, and finishes well.
Odor: No characteristic odor.
Allergies/Toxicity: Birch in the Betula genus has been reported as a sensitizer. Usually most common reactions simply include skin and respiratory irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses: Plywood, boxes, crates, turned objects, interior trim, and other small specialty wood items.
Comments: Birch is one of the most widely used woods for veneer and plywood worldwide. Besides regular sheets of plywood, Birch veneer is also used for doors, furniture, and paneling.
