1,010 lbf — Medium (Janka); typical published value for black walnut.
Durability & Decay Resistance
Moderately durable; heartwood has some decay resistance, while sapwood is less resistant to insects and rot.
Value & Age
Roughly US$8–20 per board foot for typical lumber; grade, thickness, region, and milling can change this substantially.
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 reliably estimated from this image; the subdued color and marks do not establish age or provenance.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, carving, and turned objects.
Geographic Origin
Eastern North America, especially the central and eastern United States.
Workability
Generally machines and sands well and glues readily; sharp tools help limit tearout on irregular grain. Pre-drilling is useful for fasteners near edges.
Finish Recommendations
Sand evenly and use oil, shellac, lacquer, or clear polyurethane; a clear finish helps retain the brown color. Test first, as appearance may shift with finish.
Notable Features
Valued for its rich brown heartwood and attractive color variation; this sample’s surface appears weathered or dusty, limiting visual assessment.
