Under natural conditions in Cote d'Ivoire an average annual diameter increment of 2.9 mm was recorded, and in Ghana it was 3.2 - 5.5 mm.

]. It is usually fairly easy to saw and work, with moderate blunting effects on cutting edges because the wood contains some silica (up to 1.0%). It can be finished to a smooth surface, but there may be a slight tendency to pick up in planing quarter-sawn material and gum may appear at the surfaces. The wood holds nails and screws well, but may split upon nailing. It glues satisfactorily except when gum is present; the use of a filler is recommended for staining and polishing. The bending properties are usually satisfactory. The heartwood is strongly resistant to impregnation, the sapwood permeable to moderately resistant. The wood is valued for house building, flooring, joinery, interior trim, panelling, window frames, doors, ship building, vehicle bodies, furniture, cabinet work, decorative boxes, crates, veneer and plywood. It is suitable for musical instruments, toys, novelties, carving and turnery, but gum exudation may have adverse effects on the products[
