Grain Pattern
Straight to interlocked grain pattern with a fine, uniform texture.

3,680 lbf (Extremely Hard)
Durability & Decay Resistance
Very Durable; exceptional natural resistance to rot, fungal decay, moisture, and insect attacks including termites.
Value & Sustainability
- Estimated Market Value
- $8.00 to $15.00 per linear foot ($10.00 to $18.00 per board foot depending on thickness and width).
- Wood Age Estimate
- Estimated installation age of 5 to 15 years based on surface oxidation, lichen growth along seams, and weathered silvering.
- Sustainability Status
- Listed on CITES Appendix II to control international trade and combat deforestation; FSC-certified sourcing is available but increasingly restricted.
Common Uses
Outdoor decking, boardwalks, docks, exterior siding, heavy construction, outdoor furniture, and commercial landscaping.
Geographic Origin
Central and South America (primarily Brazil and surrounding tropical regions).
Workability
Difficult to work due to extreme density and hardness; rapidly dulls cutting tools, requires carbide-tipped blades and pre-drilling for fasteners, and glues with difficulty.
Finish Recommendations
Requires deep-penetrating exterior hardwood oil finishes with UV inhibitors (e.g., Penofin or Messmer's) after power washing or brightening; film-forming finishes like varnish will fail and peel.
Notable Features
Extremely dense (sinks in water), class A fire rating equivalent to concrete/steel, high oil and lapachol yellow dust content, and exceptional structural longevity.
