AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Matured timber sample, showing surface weathering and drying micro-checking typical of air-dried exterior timberaged several years.
Common Uses
Outdoor decking, boardwalks, heavy marine construction, docks, outdoor furniture, siding, and heavy-duty industrial flooring.
Geographic Origin
Central and South America (principally Brazil and Bolivia)
Workability
Difficult to work due to extreme density and hardness; rapidly dulls cutting edges. Pre-drilling required for fasteners. Glues moderately well with proper surface preparation to clear natural oils.
Finish Recommendations
Penetrating oil finishes specifically designed for dense hardwoods (e.g., ipé oil). Unfinished wood naturally weathers to a silvery-grey patina over time.
Notable Features
Extremely dense and heavy (sinks in water); highly fire-resistant (Class A fire rating comparable to concrete/steel); contains lapachol yellow powder within pores which can act as a skin/respiratory sensitizer.
