Hardness Rating
1,010 lbf (Medium)
Durability Rating
Durable; very resistant to heartwood decay, though sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, interior paneling, gunstocks, and turned objects.
Geographic Origin
Eastern North America
Market Value & Sustainability
Estimated Market Value
$10.00 - $18.00 per board foot depending on grade and width.
Wood Age Estimate
The sample appears modern with industrial sanding and a light surface oxidation suggesting 5-10 years since milling.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable in its native range.
Workability
Excellent workability with both hand and machine tools. Planes and glues well. Can occasionally exhibit surface tearout in areas of irregular grain.
Notable Features
Distinctive mild, earthy scent when worked. Known for high dimensional stability. Dust can be a mild irritant to some users.
Finish Recommendations
Wipe-on oils or polyurethane to enhance depth and grain. Avoid heavy stains that mask the natural luster.
Identification Confidence
High. The distinctive cathedral grain patterns, deep brown coloration, and semi-porous surface texture are hallmarks of American Black Walnut.
