Iroko
Milicia excelsa • Exotic/Tropical Hardwood
Grain Pattern
Interlocked grain with a medium to coarse texture; features a somewhat irregular, ribbon-stripe pattern when quarter-sawn and large, open pores.
Color Description
Heartwood is initially a yellow-to-golden brown, darkening to a darker teak-like chocolate brown over time with light exposure. Sapwood is a distinct pale yellow.
Hardness Rating
1,260 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and insect attack, frequently used as a Teak substitute for outdoor applications.
Common Uses
Veneer, flooring, boat building, outdoor furniture, cabinetry, and turned objects.
Geographic Origin
Tropical Africa (East and West Africa)
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot depending on thickness and region.
Wood Age Estimate
Freshly milled to slightly oxidized; the yellow-gold hue suggests it has not yet undergone significant darkening from long-term UV exposure.
Sustainability Status
Listed as Near Threatened on the IUCN Red List; not currently CITES listed but subject to harvesting regulations in some regions.
Workability
Generally easy to work, though interlocked grain can cause tearout during planing. Contains calcium carbonate deposits which can severely dull tool cutters. Gluing and finishing are excellent.
Notable Features
Often called African Teak; lacks the oily feel of true teak but has similar stability. Dust can be a sensitizer causing respiratory irritation.
Finish Recommendations
Takes all finishes well; oil finishes enhance the golden-brown chatoyance, while lacquer or polyurethane provide durable protection for high-wear surfaces.
Identification Confidence
Medium-High; the coarse texture, golden-yellow color, and large pore structure are classic indicators of Iroko (Milicia excelsa).
