AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Modern sample; likely less than 5 years old based on the fresh milling marks, tongue-and-groove profile, and lack of oxidation.
Common Uses
Outdoor decking, flooring, railroad ties, heavy construction, dock surfaces, and cabinetry.
Geographic Origin
Central America and Northern South America (Amazon Basin)
Workability
Difficult due to extreme density and interlocked grain. Causes significant dulling of cutting edges; pre-drilling is essential for screws. Glues well if surface oils are wiped with solvent.
Finish Recommendations
Penetrating oil finishes (such as Ipe oil) are best for outdoor use. For indoor use, water-based or oil-based polyurethanes work well, but may require a dewaxed shellac sealer first.
Notable Features
Faint vanilla or cinnamon-like scent when worked (due to coumarin content). High density makes it sink in water. It has very high oily content which aids in weather resistance.
