Common Name(s): Bigtooth Aspen

Scientific Name: Populus grandidentata

Distribution: Northeastern North America

Tree Size: 65-80 ft (20-25 m) tall, 1.5-2 ft (.6-.7 m) trunk diameter

Average Dried Weight: 27 lbs/ft3 (435 kg/m3)

Specific Gravity (Basic, 12% MC): .36, .43

Janka Hardness: 420 lbf (1,870 N)

Modulus of Rupture: 9,100 lbf/in2 (62.8 MPa)

Elastic Modulus: 1,430,000 lbf/in2 (9.86 GPa)

Crushing Strength: 5,300 lbf/in2 (36.6 MPa)

Shrinkage: Radial: 3.3%, Tangential: 7.9%, Volumetric: 11.8%, T/R Ratio: 2.4

Color/Appearance: Heartwood tends to be a light brown. Wide sapwood is a pale yellow to nearly white, and isn’t clearly demarcated, tending to gradually blend into the heartwood.

Grain/Texture: Grain is generally straight, with a uniform medium texture. Low natural luster.

Endgrain: Diffuse-porous; solitary and radial multiples; medium pores in no specific arrangement, moderately numerous to numerous; parenchyma marginal; narrow rays, spacing fairly close.

Rot Resistance: Rated as non-durable, and also susceptible to insect attack.

Workability: Easy to work with hand and machine tools, though sharp cutters are necessary when planing to avoid fuzzy surfaces, (subsequent fine-sanding may be necessary to obtain a smooth surface). Does not split easily, and has poor nail-holding capability. Wood has a tendency to warp and distort during drying. Glues and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Bigtooth Aspen. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Aspen is commonly harvested as lumber, and is used for pulpwood in paper manufacture. Wide planks of Aspen lumber should be available within its natural range for a modest price.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Boxes/crates, veneer, plywood, and various utility purposes.

Comments: No data available.
