Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; very resistant to heartwood decay, though susceptible to insect attack.

High-end furniture, cabinetry, veneer, gunstocks, interior trim, and flooring.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot for premium domestic lumber.
Wood Age Estimate
Modern processing; likely harvested within the last 10-20 years based on the uniform factory-applied finish and lack of deep oxidation patina.
Sustainability Status
Not CITES listed; classified as Least Concern by the IUCN; widely available as FSC certified.
Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes very well, though it can produce a distinct odor when cut.
Notable Features
Distinctive mild, spicy scent when worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung or Danish oil) to enhance depth; clear polyurethane for durability in high-traffic areas like tables.
Identification Confidence
High; the deep brown color tone, pore structure, and characteristic grain swirl are quintessential markers of American Black Walnut.
