Silver Birch

Common Name(s): Silver Birch

Scientific Name: Betula pendula

Distribution: Europe and southwest Asia

Tree Size: 65-100 ft (20-30 m) tall, 1-2 ft (.3-.6 m) trunk diameter

Average Dried Weight: 40 lbs/ft3 (640 kg/m3)

Specific Gravity (Basic, 12% MC): .50, .64

Janka Hardness: 1,210 lbf (5,360 N)

Modulus of Rupture: 16,570 lbf/in2 (114.3 MPa)

Elastic Modulus: 2,024,000 lbf/in2 (13.96 GPa)

Crushing Strength: No data available

Shrinkage: No data available

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, 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 marginal, 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. Figured boards can be more expensive, but normally plain birch lumber is in the same price range as maple or oak.

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.
