Iroko
Milicia excelsa • Exotic/Tropical
Grain Pattern
Interlocked, medium to coarse texture with open pores and a slightly irregular appearance.
Color Description
Yellow to golden brown heartwood that darkens to a deep brown over time. Sapwood is pale yellow and clearly demarcated. The wood has a moderate natural luster.
Hardness Rating
1,260 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and insect attack, commonly used as a substitute for Teak.
Common Uses
Boat building, outdoor furniture, flooring, cabinetry, veneer, and light construction.
Geographic Origin
Tropical Africa (West and East Africa)
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 - $18.00 per board foot depending on thickness and width.
Wood Age Estimate
Modern cut (less than 10 years) based on lack of significant oxidation or deep patina on the surface.
Sustainability Status
IUCN Red List: Near Threatened; not currently CITES listed but subject to harvesting restrictions in some countries.
Workability
Generally easy to work with tools, although interlocked grain can cause tearout during planing. Significant dulling effect on cutters due to calcium carbonate deposits.
Notable Features
Often called 'African Teak,' though it is unrelated. Dust is a known sensitizer and can cause respiratory irritation or skin rashes.
Finish Recommendations
Takes glues and finishes well. Due to natural oils, a sealer or polyurethane is recommended for outdoor use to preserve color.
Identification Confidence
Medium; the coarse, interlocked grain and golden-brown hue are characteristic of Iroko, though some species of Meranti or Genuine Mahogany share similar face grain characteristics.
