Heartwood is a golden brown to deep reddish brown; it darkens significantly upon exposure to light. Sapwood is yellowish-white and clearly demarcated.
Hardness Rating
1260 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and insect attack, frequently used as a Teak substitute.
Common Uses
Boat building, flooring, outdoor furniture, cabinetry, veneer, and turned objects.
Geographic Origin
Tropical Africa (West and East Africa)
Market Value & Sustainability
Estimated Market Value
$12.00 - $18.00 per board foot
Wood Age Estimate
Modern lumber; likely kiln-dried or air-dried within the last 5-10 years based on surface oxidation and sharp mill edges.
Sustainability Status
Listed on the IUCN Red List as Near Threatened; not CITES listed but subject to harvesting regulations in certain countries.
Workability
Generally easy to work, though interlocked grain can cause tearout during planing. Contains calcium carbonate deposits which can dull cutting edges.
Notable Features
Often lacks a distinct scent when dry; known for its high natural oil content and excellent stability.
Finish Recommendations
Takes most finishes well, though oil-based finishes highlight the ribbon figure best. Use of a grain filler is recommended for a smooth surface.
Identification Confidence
Medium-High; the reddish-brown hue, ribbon-like interlocked grain, and coarse texture are classic indicators of African Iroko.
