Grain Pattern
Interlocked, tight grain with a fine to medium texture; exhibits a relatively uniform, straight appearance in long-grain cuts but with subtle waves.

Hardness (Janka)
3,510 lbf (Extremely Hard)
Durability & Decay Resistance
Very Durable; outstanding resistance to rot, termites, and fungal decay. Often cited as having a fire rating similar to concrete or steel.
Value & Sustainability
- Estimated Market Value
- $15.00 to $25.00 per board foot depending on dimensions and FSC certification.
- Wood Age Estimate
- Indeterminate based on image; however, the surface oxidation suggests it has been exposed to ambient light for at least several months.
- Sustainability Status
- Listed in CITES Appendix II as of 2024; IUCN status varies by specific species within the genus, often listed as Vulnerable due to over-harvesting.
Common Uses
Outdoor decking, boardwalks, heavy marine construction, bridges, flooring, and pool surrounds.
Geographic Origin
Central and South America (widely distributed in Brazil).
Workability
Difficult to work due to extreme density and hardness. It has a high blunting effect on cutters; carbide tooling and pre-drilling for all fasteners are mandatory. Gluing can be difficult due to natural oils.
Finish Recommendations
Penetrating oil finishes (specifically formulated for hardwoods) are best to maintain color. If left unfinished, it will weather to a silver-grey patina.
Notable Features
Extremely heavy (sinks in water); produces a distinct yellow/green powder (lapachol) when cut which can cause skin irritation; virtually no odor.
