Grain Pattern
Interlocked grain with a medium to coarse texture, exhibiting a fairly distinct ribbon stripe pattern on quartersawn surfaces and open pores typical of the Moraceae family.

Hardness (Janka)
1,260 lbf (Hard)
Durability & Decay Resistance
Very Durable. High resistance to rot and insect attack, often used as a substitute for Teak in maritime environments.
Value & Sustainability
- Estimated Market Value
- $10.00 - $15.00 per board foot depending on thickness and width.
- Wood Age Estimate
- Relatively recent mill stock, estimated 1-5 years post-harvest based on the crisp edges and surface oxidation levels visible on the right plank.
- Sustainability Status
- Listed as Near Threatened on the IUCN Red List; some regions require FSC certification for sustainable export.
Common Uses
Boat building, outdoor furniture, flooring, cabinetry, heavy construction, and veneer.
Geographic Origin
Tropical Africa (from Ivory Coast to Ethiopia and south to Angola and Mozambique).
Workability
Generally easy to work, though interlocked grain can cause tearout during planing. Contains calcium carbonate deposits which can dull cutting edges quickly.
Finish Recommendations
Takes stains and finishes well, but if used outdoors, periodic application of teak oil helps maintain color; otherwise, it will weather to a silver-grey.
Notable Features
Often referred to as African Teak due to its similar appearance and durability, though it is unrelated. Dust can be a sensitizer/irritant to eyes and skin.
