Ipe (Brazilian Walnut)
Handroanthus spp. (formerly Tabebuia) • Exotic/Tropical
Grain Pattern
Very fine, straight to interlocked grain. Smooth, uniform texture with very small pores visible in the exposed cross-section.
Color Description
Heartwood is a deep reddish-brown to yellowish-olive; often develops a grayish patina if weathered. Freshly cut areas show a distinctive yellowish-olive hue. High luster.
Hardness Rating
3,684 lbf (Extremely Hard)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and wood-boring insects. Rated for 25+ years of ground contact.
Common Uses
High-end decking, boardwalks, exterior furniture, flooring, tool handles, bridge construction, and turnery.
Geographic Origin
Central and South America (primarily Brazil) and parts of the Caribbean.
Market Value & Sustainability
Estimated Market Value
$15.00 - $22.00 per board foot (pricing varies widely by dimension and grade).
Wood Age Estimate
The sample appears to be seasoned lumber with some surface oxidation; estimated 2-5 years post-harvest.
Sustainability Status
Some species are CITES Appendix II listed. Increasingly regulated due to over-harvesting; FSC certification is highly recommended for ethical sourcing.
Workability
Extremely difficult to work. High density and interlocked grain frequent cause tool dulling. Requires carbide-tipped blades. Pre-drilling is mandatory for fasteners.
Notable Features
Extremely heavy/dense (sinks in water). Known for high fire rating (Class A). Natural oils offer moisture protection but can interfere with glue and finish.
Finish Recommendations
Natural oils (like Penofin) are best. Conventional film finishes like polyurethane often fail or peel due to the wood's natural oils and density.
Identification Confidence
High. The characteristic olive-yellow interior revealed by the fracture, coupled with the extremely dense texture and dark weathered exterior, is diagnostic of Ipe.
