Black Walnut

Juglans nigraHardwood

Black Walnut

Grain Pattern

Semi-ring-porous with visible growth rings on the end grain. The face grain appears generally straight to slightly irregular with a subtle cathedral figure and some wavy characteristics typical of kiln-dried walnut.

Color Description

Medium to dark chocolate brown heartwood, sometimes with a purplish or reddish cast. Sapwood (visible on edges) is a pale yellowish-gray. It typically lightens over time with UV exposure, unlike most woods.

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, gunstocks, interior trim, flooring, veneer, and wood turning.

Geographic Origin

Eastern North America (United States and Canada)

Market Value & Sustainability

Estimated Market Value

$10.00 - $15.00 per board foot depending on thickness and width

Wood Age Estimate

Freshly milled/modern stock. The rough-sawn surface and lack of significant oxidation or deep patina suggest this is industrial lumber produced within the last 5-10 years.

Sustainability Status

Highly sustainable; not listed on CITES or IUCN Red List. Widely available and FSC certified sources exist.

Workability

Excellent. Works easily with both hand and machine tools. Glues, stains, and finishes very well, though it is usually left natural due to its inherent beauty.

Notable Features

Distinctive mild, spicy scent when being worked. Known for its shock resistance and dimensional stability. Dust can be a sensitizer for some users.

Finish Recommendations

Oil-based finishes (Tung or Linseed oil) to deepen the color, or clear polyurethane/lacquer to preserve look. Does not require stain.

Identification Confidence

High. The chocolate brown color, distinct pale sapwood, ring-porous end grain structure, and typical rough-sawn texture are classic indicators of Juglans nigra.
