Common Name(s): African Mahogany

Scientific Name: Khaya spp. (Khaya anthotheca, K. grandifoliola, K. ivorensis, K. senegalensis)

Distribution: West tropical Africa

Tree Size: 100-130 ft (30-40 m) tall, 3-5 ft (1-1.5 m) trunk diameter

Average Dried Weight: 40 lbs/ft3 (640 kg/m3)

Specific Gravity (Basic, 12% MC): .52, .64

Janka Hardness: 1,070 lbf (4,760 N)

Modulus of Rupture: 13,190 lbf/in2 (91.0 MPa)

Elastic Modulus: 1,537,000 lbf/in2 (10.60 GPa)

Crushing Strength: 7,100 lbf/in2 (49.0 MPa)

Shrinkage: Radial: 4.2%, Tangential: 5.7%, Volumetric: 10.0%, T/R Ratio: 1.4

Color/Appearance: Heartwood color is variable, ranging from a very pale pink to a deeper reddish brown, sometimes with streaks of medium to dark reddish brown. Color tends to darken with age. Quartersawn surfaces can also exhibit a ribbon-stripe appearance.

Grain/Texture: Grain is straight to interlocked, with a medium to coarse texture. Good natural luster with a light-refracting optical phenomenon known as chatoyancy. (See video below.)

Endgrain: Diffuse-porous; large to very large pores, very few; solitary and radial multiples; orange/brown deposits occasionally present; growth rings usually indistinct, though sometimes distinct due to terminal parenchyma; rays medium to wide, fairly close spacing; parenchyma scanty to vasicentric, and occasionally marginal (not typical for Khaya spp.).

Rot Resistance: Rated as moderately durable; moderate to poor insect/borer resistance.

Workability: Easy to work, glue, and finish. Tearout can sometimes be a problem if the grain is interlocked.

Odor: No characteristic odor.

Allergies/Toxicity: Although severe reactions are quite uncommon, African Mahogany has been reported as a sensitizer. Usually most common reactions simply include eye and skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Readily available in a variety of lumber sizes. Prices are low to moderate for an imported hardwood.

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, turned items, furniture, boatbuilding, and interior trim.
