African Mahogany wood properties

Also known as: khaya, acajou d'afrique.

Type hardwood
Botanical name Khaya spp.
Modulus of elasticity (MOE) 1,410,000 psi
Specific gravity 0.54
Density (approx) 34 lb/ft³ (2.8 lb per board foot)
Janka hardness 850 lbf
Shrinkage (tangential / radial) 5.7% / 3.4%
Region Tropical Africa

A 1 in x 6 in x 8 ft board of African Mahogany weighs about 11.2 lb (roughly 34 lb per cubic foot). Its Janka hardness of 850 lbf is harder than about 37% of the woods in our database.

Uses and working notes

Common uses: furniture, cabinetry, interior trim, boatbuilding, turned items, veneer.

Durability: Moderately durable; insect and borer defense ranges from fair to weak.

Workability: Fairly easy, though interlocked grain tears; damp iron fasteners may stain it; finishes, turns and glues cleanly.

How these numbers were sourced

MOE, SG (12% MC), Janka and shrinkage from The Wood Database (cites USDA FPL Wood Handbook). African Mahogany is not listed in the FPL/Hoadley dimensional change coefficient table, so CT/CR are omitted. Uses, region, durability and workability summarized from The Wood Database. Price indicative.

These calculators are for planning and estimation. Engineering results (shelf sag, wood movement) use published average material properties; real boards vary by grade, grain, moisture and defects. Verify load-bearing designs with a professional.
