Iroko

Milicia excelsa, Milicia regiaExotic/Tropical

Iroko

Grain Pattern

Interlocked, which can lead to ribbon-like figures on quartersawn surfaces; texture is medium to coarse with open pores.

Color Description

Heartwood is typically a yellow-to-golden brown, darkening to a rich brown over time with light exposure. Sapwood is a clearly demarcated pale yellow.

Hardness Rating

1,260 lbf (Hard)

Durability Rating

Very Durable; excellent resistance to rot and insect attack, including termites; often used as a substitute for Teak.

Common Uses

Veneer, flooring, boat building, outdoor furniture, cabinetry, turned objects, and specialty small wood items.

Geographic Origin

Tropical Africa (widely distributed from West to East Africa).

Market Value & Sustainability

Estimated Market Value

$10.00 - $15.00 per board foot, depending on location and quality grade.

Wood Age Estimate

Relatively fresh/recent cut, as evidenced by the lack of significant deep oxidation or weathering, likely less than 2-5 years since milling.

Sustainability Status

IUCN Red List: Near Threatened; not listed on CITES Appendices, but FSC certification is available and recommended.

Workability

Generally easy to work, though interlocked grain can cause tearout during planing. High mineral/silica content can have a significant dulling effect on cutters.

Notable Features

Often lacks a distinctive odor when working; contains calcium carbonate deposits which can create white streaks or damage tools; potential for respiratory irritation.

Finish Recommendations

Takes stains and finishes well, though a grain filler is recommended to achieve a smooth surface due to large pores. Lacquer and oil finishes are common.

Identification Confidence

High; the coarse, interlocked grain coupled with the specific golden-brown hue and visible mineral deposits are characteristic indicators of Iroko.
