Grain Pattern
Interlocked grain with a medium to coarse texture. Visible checks and surface weathering suggest a flat-sawn or rift-sawn orientation with significant outdoor exposure.
Color & Appearance
Initially yellow, darkening to golden brown or dark brown over time. This sample shows significant silver-gray weathering and oxidation due to UV exposure and outdoor environment.
Hardness (Janka)
1,260 lbf (Hard)
Durability & Decay Resistance
Very Durable. Highly resistant to rot, insect attack, and fungal decay; often used as a more affordable substitute for Teak.
Value & Sustainability
- Estimated Market Value
- $10.00 to $15.00 per board foot depending on thickness and quality.
- Wood Age Estimate
- The grey patina and surface checking suggest the wood has been exposed to the elements for 2 to 5 years.
- Sustainability Status
- IUCN Red List: Lower Risk/Near Threatened; not currently CITES listed, but under monitoring due to habitat loss and over-exploitation.
Common Uses
Outdoor furniture, decking, boat building, flooring, cabinetry, and heavy construction.
Geographic Origin
Tropical Africa (West and East Africa)
Workability
Generally good, though interlocked grain can cause tearout during planing. High silica content can dull blades quickly. Glues and finishes well once surface oils are cleaned.
Finish Recommendations
Penetrating oils or teak oils are recommended for maintenance. If the silver-grey look is desired, it can be left unfinished. Sanding is required to restore original golden tones.
Notable Features
Often referred to as "African Teak." Known for high oil content and exceptional stability in humid environments. Dust can be a potent sensitizer/irritant.
