Shrinkage: Radial: 7.3%, Tangential: 9.5%, Volumetric: 16.8%, T/R Ratio: 1.3

Color/Appearance: Heartwood tends to be a light reddish brown, with nearly white sapwood. Occasionally figured pieces are available with a wide, shallow curl. 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, with a fine, even texture. Low natural luster.

Endgrain: Diffuse-porous; primarily radial multiples; medium pores in no specific arrangement, moderately numerous to numerous; parenchyma maringal, and sometimes diffuse-in-aggregates (faintly visible with lens); narrow rays, spacing fairly close to close.

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.

Pricing/Availability: Likely to be rather economical in most instances.

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.
