Iroko wood

タイトルまたは説明

Iroko is a very tough, durable wood that has been traditionally used in a multitude of applications in its native Africa. Its golden to medium brown color, course texture and interlocked grains give it an appearance very similar to that of Teak; although it is significantly less dense, it has been utilized in Africa in many of the same functions / duties that Teak has in other parts of the world. Despite its toughness (and interlocked grains), it is generally not difficult to work; it glues and finishes well.
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.
