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, figure mottled. The wood is somewhat greasy and is odourless. Iroko is a highly valued commercial timber in Africa, for which demand is large.

​

Seasoning

Stability

moderately stable

​

Durability

Iroko is very durable, and is resistant to both rot and insect attack

​

Workability

Working properties for hand and machine tools are generally good but variable; the interlocked grain may hamper sawing and planing. The wood is rather abrasive due to the presence of hard deposits (‘iroko stones’, mainly consisting of calcium carbonate), which can blunt cutting edges. Tearing in planing can be avoided by using cutting angles of 15° or less. The wood has good nailing, screwing, mortising and gluing properties and turns easily. It finishes well, but filler is needed. The wood contains the stilbene derivative chlorophorin, which prevents oil-based paints from drying, and which corrodes metal in contact with it. Steam-bending properties of the wood are moderate.
