Africa. It is original of the tropics of Central and West Africa, from Nigeria to the Congo region and Southern Angola.
- Sapwood: Whitish.
- Heartwood: Intense red that darkens into dark brown due to light effects. It frequently has dark brown streaks.
- Fiber: Straight. Slightly intertwined fibers are very frequent.
- Grain: Medium size to rough.
- Defects: White deposit bags.
- Apparent density at 12 % humidity: 740 kg/m3. Heavy Wood.
- Dimensional stability:
- Volumetric contraction coefficient 0,36 %. Stable Wood.
- Relation between contractions 1,60 %. No tendency to deformity.
- Hardness (Chaláis-Meudon) 6,9. Hard wood.
- Interior furniture and cabinet work.
- Exterior furniture and cabinet work.
- Carved and turned furniture.
- Interior carpentry: doors, paneling, molding, baseboards, friezes and stairs.
- Exterior carpentry: doors and windows.
- Decorative panels.
- Resistance to static flexion: 1,450 kg/cm2.
- Elasticity module: 124,000 kg/cm2.
- Resistance to compression: 650 kg/cm2.
- Sawing process: Hard and with some abrasive effects.
- Drying process: Medium to low speed. Little risk of deformation and crack formation.
- Planing process: Apart from hardness difficulties, risk of repelling is very frequent in those cases of intertwined fibers. Suitable for carving and bending.
- Gluing process: Certain difficulties due to the oil content.
- Nailing and screwing process: Pre-drilling is required.
- Finish: No difficulties.
Capacity of being Impregnated
- Sapwood: Capable of being impregnated.
- Heartwood: Medium capacity of being impregnated.
