		Iroko Botanical Name: Chlorophora excelsa Common Name(s): Odum Origin: West Africa
OverviewBasic InfoTechnical General: The wood is hard and of medium weight. It is variable in colour from yellow to fairly dark brown. Grain is typically interlocked. Texture is medium to coarse and even. It has neither taste nor odour. Darkens with age. Seasoning: Requires reasonable care in kiln drying to avoid degrade. Working: Works with moderate ease with most hand and machine tools and finishes well. Stone-like calcareous deposits are sometimes present and these may cause damage to cutting edges. In planing quarter-sawn material the cutting angle should be reduced to 15º to avoid picking-up of the grain. It nails, screws and glues well. Although requiring a grain filler, the wood takes stain well and gives good results with polish. It can be cut into veneer and it has moderate steam-bending qualities. Uses: In the United Kingdom it is used for many purposes and is suitable for high grade joinery, interior fittings, window frames, doors, staircases, heavy furniture and laboratory benches, bank and shop fittings, boat and vehicle building, wagon work and flooring. It is also suitable for piling, dock and other constructional work. In the UK Iroko is often used as a substitute for Teak.
