Black Walnut
Juglans nigra • Hardwood
Grain Pattern
Straight grain in most sections with cathedral figure showing in the flatsawn areas; medium texture with semi-porous growth rings
Color Description

Hardness Rating
1010 lbf (Medium)
Durability Rating
Durable and very resistant to decay; however, the sapwood is susceptible to insect attack.
Common Uses
High-end furniture, cabinetry, veneer, gunstocks, interior trim, flooring, and small specialty turned objects.
Geographic Origin
Eastern United States and Canada (Eastern North America)
Market Value & Sustainability
Estimated Market Value
Ranges from $10.00 to $16.00 per board foot depending on thickness and grade (Select and Better).
Wood Age Estimate
Relatively recent milling; the lack of deep oxidation and the clean machine-cut edges suggest the sample is less than 5 years old.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List of Threatened Species; widely available and generally managed sustainably in North America.
Workability
Excellent workability with both hand and machine tools. Planes well, glues easily, and takes stains and finishes exceptionally. Can occasionally have brittle grain in figured areas.
Notable Features
Distinctive mild and pleasant scent when being worked; relatively lightweight for its strength; contains juglone which can be a mild irritant to some users.
Finish Recommendations
Oil-based finishes (tung or linseed) or polyurethane are recommended to highlight the deep colors and chatoyance; clear lacquer also works well for a high-build look.
Identification Confidence
High; the characteristic chocolate-brown heartwood, pore structure, and contrast between sapwood and heartwood are typical of Juglans nigra.
