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 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.
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 heartwood is a light golden-yellow with narrow veining or streaks of dark brown to almost black, giving the quartered surfaces a zebra-stripe appearance. The grain is interlocked or wavy and produces alternating hard and soft grained material which makes the timber difficult to work. Zebrano has a coarse texture and a lustrous surface. Weight 740 kg/m³ (46 lb/ft³); specific gravity .74.

The wood is laced with closely spaced whitish bands of parenchyma, giving wenge an attractive appearance. It is fairly straight grained and has a coarse texture. With a weight of 880 kg/m³ (55 lb/ft³) and a specific gravity of 0.88, wenge is a relatively hard and heavy wood.
Balau’s heartwood is yellow-brown, varying to brown and dark reddish-brown, with an interlocked grain and a moderately fine and even texture. It has a coarse texture with medium to large pores and the grain is sometimes interlocked. The weight of balau averages 930 kg/m³ (58 lb/ft³); specific gravity .93.
