Iroko
Milicia excelsa & Milicia regia • Exotic/Tropical Hardwood
Grain Pattern
Interlocked, creating a ribbon-like figure on quarter-sawn surfaces. Texture is coarse to medium with open pores and some wavy grain visible.
Color Description
Heartwood is typically a yellow-to-golden brown, darkening to a deep brown over time. Grain often displays chatoyancy. Sapwood is clearly demarcated, being a pale yellow-white.
Hardness Rating
1260 lbf (Hard)
Durability Rating
Very Durable. Excellent resistance to rot, termites, and fungal attack; often used as a Teak substitute for outdoor use.
Common Uses
Outdoor furniture, boat building, flooring, cabinetry, turned objects, and specialty exterior joinery.
Geographic Origin
Tropical Africa (West and East Africa regions)
Market Value & Sustainability
Estimated Market Value
$10.00 - $15.00 per board foot
Wood Age Estimate
The visible darkening and patina suggest this sample is at least 5-10 years post-harvest or has been exposed to UV light to reach its deep bronze hue.
Sustainability Status
Listed on the IUCN Red List as Near Threatened; not currently CITES listed, but availability of FSC certified stock varies.
Workability
Generally easy to work with machine and hand tools, though interlocked grain can cause tearout during planing. Contains calcium carbonate deposits which can dull cutting edges.
Notable Features
Often called 'African Teak' though unrelated. Wood dust can be a potent sensitizer causing respiratory irritation. Excellent stability once dried.
Finish Recommendations
Takes stains and finishes well. Due to natural oils and coarse texture, a grain filler may be needed for a high-gloss finish; penetrating oils or polyurethane are recommended.
Identification Confidence
High. The distinctive interlocking grain, bronze-brown color transition, and visible vessel lines are characteristic of Milicia species.
