Hardness Rating

1,010 lbf (Medium)

Durability Rating

Very Durable; highly resistant to heartwood decay, though susceptible to insect attack.

High-end furniture, cabinetry, gunstocks, interior trim, flooring, veneer, and turned objects.

Geographic Origin

Eastern North America (United States and Canada)

Market Value & Sustainability

Estimated Market Value

Approximately $12.00 - $18.00 per board foot for Select & Better grade.

Wood Age Estimate

Modern processing, likely 5-20 years old based on the smooth surface preparation and contemporary finish application.

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List of Threatened Species; widely available and generally sustainable.

Workability

Excellent workability with both hand and machine tools. Planes well, glues easily, and takes stains and finishes very well. Can sometimes have irregular grain that causes tearout.

Notable Features

Faint, mild odor when being worked. Known for its unique dark color among temperate hardwoods and excellent dimensional stability.

Finish Recommendations

Usually finished with clear coats (oil-based polyurethane or lacquer) to highlight natural color; penetrating oils like Teak or Danish oil enhance the depth of the grain.

Identification Confidence

High; the characteristic chocolate-brown hue, diffuse-porous structure with visible vessel lines, and growth ring patterns are distinct to Black Walnut.
