Tree description
Afrormosia is a large tree reaching heights of 30-50 m (98-164 ft). The straight and cylindrical trunk is 60-160 cm (2-5 ft) in diameter, and is clear of branches for up to 30 m (98 ft). The scale-like bark is fibrous with strong red marks.

Property and application
Azobe is firm and heavy, being amongst the hardest usable woods in the world, and is largely impervious to the effects of insects and weather. These qualities make it a first-class construction timber with tremendous longevity. However, drying must be done slowly, and at low temperature, to avoid breakage or distortions. Examples of Azobe’s many uses are bridge construction, the building of railway sleepers and freight cars, and vehicle construction. In addition, it is used for wood decking, heavy lumber beams, and the production of laboratory furniture.
