Black Walnut

Grain Pattern

Generally straight to irregular; this sample shows distinct cathedral and slightly wavy figure typical of flat-sawn walnut heartwood. Moderate, open texture.

Hardness Rating

1,010 lbf (Medium)

Durability Rating

Durable to Very Durable regarding decay resistance; resistant to heartwood rot, though susceptible to insect attack (sapwood).

Common Uses

High-end furniture, cabinetry, veneer, gunstocks, interior trim, flooring, and musical instruments.

Geographic Origin

Eastern United States and parts of Southern Canada.

Market Value & Sustainability

Estimated Market Value

Approximately $12.00 - $18.00 per board foot for select/prime grade (note: prices vary by region and board width).

Wood Age Estimate

Freshly cut/Modern; the sharp machine edges and lack of significant oxidation or patina suggest this is a contemporary offcut from industrial milling.

Sustainability Status

Abundant and sustainable; not CITES listed. Classified as Least Concern by IUCN. Widely available with FSC certification.

Workability

Excellent. It is known for its ease of use with both hand and machine tools. Glues, stains, and finishes exceptionally well, though it can occasionally produce tearout if grain is irregular.

Notable Features

Distinctive mild, spicy scent when worked. Fine dust can be a sensitizer for some users. Known for its exceptional dimensional stability.

Finish Recommendations

Penetrating oils (tung or linseed) to enhance natural figure; clear polyurethane or lacquer for durability. Does not require stain due to its natural rich pigments.

Identification Confidence

High; the deep chocolate brown color, coarse open grain structure, and characteristic figure pattern of the heartwood-sapwood transition are diagnostic of Juglans nigra.
