Ipe (Brazilian Walnut)
Handroanthus spp. (formerly Tabebuia spp.) • Exotic/Tropical Hardwood
Grain Pattern
Usually interlocked or straight; features a very fine, uniform texture. Can exhibit a subtle "partridge wood" pattern or yellowish-green lapachol deposits in the pores.
Color Description
Heartwood is typically reddish brown, often with lighter or darker streaks. Sapwood is yellowish-white to gray. Wood darkens significantly with age and light exposure; exhibits high natural luster.
Hardness Rating
3,510 lbf (Extremely Hard)
Durability Rating
Very Durable; excellent resistance to rot, termites, and wood-boring insects. Notorious for being highly resistant to weathering.
Common Uses
High-end exterior decking, boardwalks, flooring, tool handles, dock pilings, and specialty turned objects.
Geographic Origin
Central and South America (principally Brazil)
Market Value & Sustainability
Estimated Market Value
$15.00 - $25.00 per board foot (depending on dimensions and certification)
Wood Age Estimate
Post-processing sample (newly milled/cut); no significant oxidation or patina visible, indicating a fresh cut or indoor storage.
Sustainability Status
Listed in CITES Appendix II (as of late 2022). Many species are categorized on the IUCN Red List as vulnerable due to over-logging. FSC certification is common for responsible sourcing.
Workability
Difficult due to extreme hardness/density. Has a severe dulling effect on cutting edges. Hard to glue due to natural oils. Pre-drilling is mandatory for fasteners.
Notable Features
Extremely heavy (sinks in water); has the same fire rating as steel and concrete (Class A). Contains lapachol powder which can cause skin irritation.
Finish Recommendations
Penetrating oil finishes specifically designed for exotic hardwoods are best. Avoid surface films like polyurethane which may peel due to natural oils.
Identification Confidence
High; the olive-brown color, extremely dense/tight vessel structure, and classic yellowish pore deposits are characteristic of Ipe.
