Common Name(s): Obeche

Scientific Name: Triplochiton scleroxylon

Distribution: Tropical West Africa

Tree Size: 65-100 ft (20-30 m) tall, 3-5 ft (1-1.5 m) trunk diameter

Average Dried Weight: 24 lbs/ft3 (380 kg/m3)

Specific Gravity (Basic, 12% MC): .32, .38

Janka Hardness: 430 lbf (1,910 N)

Modulus of Rupture: 8,820 lbf/in2 (60.8 MPa)

Elastic Modulus: 970,000 lbf/in2 (6.69 GPa)

Crushing Strength: 4,250 lbf/in2 (29.3 MPa)

Shrinkage: Radial: 3.1%, Tangential: 5.3%, Volumetric: 8.7%, T/R Ratio: 1.7

Color/Appearance: Heartwood tends to be a pale yellow, with the sapwood not clearly differentiated from the heartwood. Colors darken slightly with age.

Grain/Texture: Grain is interlocked, with a medium to coarse texture and good natural luster.

Endgrain: Diffuse-porous; solitary and radial multiples; very large pores in no specific arrangement, very few; parenchyma vasicentric, diffuse-in-aggregates; narrow to wide rays, spacing normal.

Rot Resistance: Rated as non-durable; poor insect resistance and liable to fungal staining and discoloration if not dried promptly.

Workability: Generally easy to work, though the interlocked grain can cause some rough surfaces in some machining operations. Carves, stains, glues, and finishes well.

Odor: Has a strongly unpleasant odor when green, which mostly disappears once dried.

Allergies/Toxicity: Although severe reactions are quite uncommon, Obeche has been reported as a sensitizer. Usually most common reactions simply include eye, skin, and respiratory irritation, as well as runny nose, sneezing, hives, and asthma-like symptoms. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Lumber is sometimes available, though it’s primarily exported as veneer or plywood. Obeche is relatively inexpensive for an imported hardwood. 

Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.

Common Uses: Veneer, plywood, carvings, furniture, and interior millwork.

Comments: This African hardwood is very soft and lightweight, but has a decent strength-to-weight ratio. It’s fairly stable in service, and its bland grain patterns are frequently stained a darker color.

    Used by Paul Reed Smith Guitars Private Stock Department as bodywood with a quilted or flamed Maple top glued on it. It sounds similar to Mahogany although a little bit brighter.

    Lightweight, strong wood with minimal knots. Used for frame construction of racing boats (hydroplanes) because of strength/light weight/straightness. Can be a minor irritant when milling/sanding – recommend using a respirator/mask.
