Wood Technical Fact Sheet
Other Common Names: Adoung de heitz (Gabon).
Distribution: Reported only in northern parts of Gabon; prefers moist soils along rivers and swampy or occasionally inundated areas.
The Tree: Reaches a height of 140 ft; bole straight and cylindrical, clear to 60 ft; trunk diameters 4 to 6 ft over rather pronounced buttresses.
General Characteristics: Wood pink brown, darkens slightly on exposure; heartwood and sapwood not clearly demarcated. Texture fine and even; grain often interlocked.
Weight: Basic specific gravity (ovendry weight/green volume) 0.39; air-dry density 33 pcf.
Mechanical Properties: (2-cm standard)
Moisture content Bending strength Modulus of elasticity Maximum crushing strength
(%) (Psi) (1,000 psi) (Psi)
12% (47) 14,300 1,300 7,200
Amsler toughness 220 in.-lb at 12% moisture content (2-cm specimen).
Drying and Shrinkage: Logs should be converted soon after felling to avoid splitting. Seasons easily, but must be done slowly. No information on kiln schedules. Shrinkage green to ovendry: radial 4.0%; tangential 6.8%; volumetric 10.8%.
Working Properties: Works fairly well but tends to give a woolly finish, a reduced cutting edge angle is suggested to minimize tear due to interlocked grain; glues and nails well; easy to veneer.
Durability: Heartwood moderately durable; sapwood liable to stain and is vulnerable to powder-post beetle attack.
Preservation: Heartwood is resistant to impregnation; sapwood is permeable.
Uses: Furniture components, boxes and crates, light construction, plywood.
