Common Name(s): Okoume, Gabon

Scientific Name: Aucoumea klaineana

Distribution: Central Africa (primarily Gabon)

Tree Size: 100-130 ft (30-40 m) tall, 3-6 ft (1-1.8 m) trunk diameter

Average Dried Weight: 27 lbs/ft3 (430 kg/m3)

Specific Gravity (Basic, 12% MC): .35, .43

Janka Hardness: 400 lbf (1,790 N)

Modulus of Rupture: 10,870 lbf/in2 (75.0 MPa)

Elastic Modulus: 1,228,000 lbf/in2 (8.47 GPa)

Crushing Strength: 5,250 lbf/in2 (36.2 MPa)

Shrinkage: Radial: 4.6%, Tangential: 7.1%, Volumetric: 12.2%, T/R Ratio: 1.5

Color/Appearance: Heartwood ranges from a pale pink to light brown. Color darkens with age. Narrow heartwood is grayish white, not clearly demarcated from heartwood.

Grain/Texture: Grain is straight to wavy or slightly interlocked. Texture is medium, with good natural luster.

Endgrain: Diffuse-porous; solitary and radial multiples; large pores in no specific arrangement, few; parenchyma not visible; narrow rays, spacing normal.

Rot Resistance: Rated as non-durable; poor insect resistance.

Workability: High silica content has a pronounced blunting effect on cutters. Planing and shaping may produce tearout or fuzzy surfaces. Glues and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Although severe reactions are quite uncommon, Okoume has been reported to cause skin, eye, and respiratory irritation, as well as other effects such as asthma-like symptoms, coughing, and conjunctivitis (pink eye). See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Most commonly sold as veneer, Okoume should be moderately priced for an imported hardwood, though highly figured pieces tend to be more expensive.

Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.

Common Uses: Veneer, plywood, boatbuilding, musical instruments, furniture, and interior millwork.

Comments: Sometimes simply called Gabon (not to be confused with Gaboon Ebony), the wood is commercially important in the country of Gabon, where it’s the principle timber species. Even though it’s used almost exclusively in veneer form in the United States, solid lumber is much more common in Europe and Africa.

Related Species:

None available.

Hello. I’m shopping for a classical guitar and have run into okume wood as a neck construction material.
My interest is the weight as I seek a properly balanced instrument. Is okume a heavy wood? For example Magogany? What is the density/weight in relatio to popular resonant neck tonewood such as maple?
Thank you so much


Okoume is not a type of mahogany

Jack Huggins

Turned a bowl with alternating okoume and walnut. I was very well pleased with the result. Okoume did have a wavy appearance when finished with a friction polish.

My acoustic guitar made of this type of mahogany. Nice sound.


This is my woodturning project, shisha mouthpiece – Okoume with resin.


Id say the odor is pretty strong, even if its not being worked. Is is sweet, very distinctive smell.

What is the moisture content of okume wood found in Gabon?
