Grain Pattern

Mostly straight to slightly irregular, with attractive wavy/flame figure visible on the face; appears flat- or plain-sawn rather than quarter-sawn.

Color & Appearance

Medium chocolate-brown heartwood with lighter brown streaking and subdued luster; walnut commonly lightens or develops warmer amber tones with age and UV exposure.

Hardness (Janka)

1,010 lbf Janka — Medium.

Durability & Decay Resistance

Moderately durable; heartwood has useful decay resistance but is not intended for prolonged exterior exposure. Insect resistance is moderate.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$18 per board foot for ordinary kiln-dried lumber; figured or premium wide stock may exceed $25.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Cannot be determined from the photograph; the clean machining and limited patina suggest a relatively recent board or freshly milled stock.

Common Uses

Furniture, cabinetry, architectural millwork, gunstocks, flooring, veneer, turning, and decorative accents.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Generally machines and sands well, though irregular figure can cause localized tear-out. Glues, screws, and finishes reliably; sharp cutters improve results.

Finish Recommendations

Use a clear oil, wiping varnish, lacquer, or polyurethane; a light sealer coat can even absorption and emphasize the figure.

Notable Features

Moderate weight, attractive figure, dimensional stability, and characteristic walnut brown coloration.
