Iroko
Milicia excelsa, Milicia regia • Exotic/Tropical Hardwood
Grain Pattern
Interlocked grain with a medium to coarse texture; often shows a slightly irregular or wavy figure when quarter-sawn. Large open pores are visible.
Color Description
Initial yellow to golden brown heartwood, darkening to a deep chocolate brown over time with light exposure. Sapwood is typically narrow and pale yellow. Low to moderate natural luster.
Hardness Rating
1,260 lbf (Hard)
Durability Rating
Very Durable; excellent resistance to rot and insect attack; often used as a lower-cost substitute for Teak in marine environments.
Common Uses
Veneer, flooring, furniture, cabinetry, boatbuilding, turned items, and other small specialty wood objects.
Geographic Origin
Tropical Africa (West, Central, and East Africa)
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot
Wood Age Estimate
Freshly cut/processed (less than 1 year); lacking deep oxidation or patina typically found in aged Iroko.
Sustainability Status
IUCN Red List: Lower Risk/near threatened; not currently CITES listed but population decline is a growing concern.
Workability
Generally easy to work, but interlocked grain can cause tearout during planing. Contains calcium carbonate deposits (stone) that can dull tool cutters rapidly.
Notable Features
Often referred to as 'African Teak,' though unrelated. Can cause skin and eye irritation; sawdust is a known sensitizer. Stable once dried.
Finish Recommendations
Takes stains and finishes well, though large pores may require a grain filler for a smooth glass-like surface. Teak oil or polyurethane are recommended for outdoor use.
Identification Confidence
Medium-High; the yellowish-brown hue, coarse open pores, and stringy texture are highly characteristic of Milicia species.
