Know Your Wood: Curupay

Curupay
Dark and distinctive, Curupay, or Cebil, is a great choice for a great many applications.

Common trade names: Cebil, Curupay

Genus: Anadenanthera colubrina (syn. Anadenanthera macrocarpa)

Janka Hardness (pounds-force): 3630

Description: Curupay features deep brown to brown-red hues, characterized by prominent streaking, regularly following the grain patterns of the wood. The grain is highly interlocked and moderately figured, and Curupay has a fine to moderate texture.

Location: Latin America, specifically: Argentina, Brazil, Paraguay, Peru, Bolivia

Common Aliases: Angico, Cambui-ferro, Cebil moro, Curupay-ata, Guarapiraca

Performance: Almost as hard as any wood available, this is a fine choice for exterior application. It is highly insect and rot resistant, and is a more or less generational solution for the designer or homeowner. It’s very distinctive, and if architects or designers are searching for a wood that will “pop,” this is one species that can do the job, and can stand the test of time.

Acclimation: Please, always properly store and set aside your lumber! We can’t stress enough the importance of just a little patience when receiving your order. For air drying, simply allow a half-inch or so among parallel planks stacked and spaced by level. It’s that easy, and in two or so weeks’ time, the lumber is ready for installation in your climate!

A Curupay tree, found commonly in South America.

Common Uses: Tool handles, docks, chemical containers, foundation pilings, furniture, ground contact, vehicle parts, wharf building, exterior and interior trim, rain screen siding, shiplap, turnings.
