General Description: Iroko is golden-orange to brown, lighter vessel lines are conspicuous on flat saw surfaces. The material may contain large, hard deposits of calcium carbonate in cavities, and the timber around them may be darker in colour. The grain is interlocked and sometimes irregular and the texture rather coarse, but even. The weight is 640 kg/m³ (40 lb/ft³); specific gravity .64.
Iroko's medium density timber has a moderate steam bending classification, with medium bending and crushing strength, very low stiffness and resistance to shock loads.
Iroko dries fairly rapidly and well without much degrade and there is a tendency for stick marks to show during drying. There is a small movement in service.
The sapwood is liable to attack by powder post beetle, but is highly resistant to termites in Africa. The heartwood is very durable, and is extremely resistant to preservative treatment. The sapwood is permeable.
