Hardness (Janka)

1,350 lbf (Hard)

Durability & Decay Resistance

Very Durable, highly resistant to rot and fungal decay due to closed cellular structure (tyloses).

Value & Sustainability

Estimated Market Value
$4.00 to $8.00 per board foot depending on grade and width.
Wood Age Estimate
Modern to moderately seasoned lumber, estimated less than 10-20 years old based on clean mill marks and surface condition.
Sustainability Status
Abundant, of least concern on the IUCN Red List, widely available with FSC certification options.

Common Uses

Fine furniture, cabinetry, hardwood flooring, boat building, exterior construction, and tight cooperage (barrels).

Geographic Origin

Eastern and Central North America.

Workability

Generally good workability with hand and machine tools, though it can blunt cutters due to its hardness; reacts strongly with iron (causing dark stains in the presence of moisture).

Finish Recommendations

Takes stains, dyes, oils, and polyurethane exceptionally well; water-based finishes help preserve the natural light color without overly yellowing.

Notable Features

Contains high tannin content making it resistant to decay and reactive with iron; features closed cellular structures called tyloses that make it water-resistant.
