Species Specs: Purpleheart

Peltogyne spp. genus 
The Peltogyne spp. genus is a part of the Fabaceae family. There are more than 20 documented species of Peltogyne. This species most-commonly is known as purpleheart or amaranth, but also is known in other parts of the world as amendoim, violetwood, Palo morado, Morado, Tananeo, Koroboreli, Pau roxo, saka, nazareno, and others. These trees grow primarily in Central and South America (from Mexico down to southern Brazil).

This wood most-commonly is used in inlays, decorative woodwork pieces, as a feature strip or as flooring, furniture, boatbuilding, billiards cues, and even in heavy construction, bridge building, and chemical vats. 

Freshly cut heartwood is brown, then turns a deep eggplant purple upon exposure to air. With further age and exposure to light, the wood changes to a deep brown color with an underlying hint of purple. Minerals can cause uneven coloring. Sapwood is sharply demarcated from the heartwood with an off-white color.  

Diffuse-porous. The grain is usually straight or wavy/irregular, with a medium to fine texture and a good natural luster.

Ranges from 1,860-3,920, averaging around 2,520

Above average. The dimensional stability factor is 3.8 percent (radial) and 6.4 percent (tangential), meaning these species may shrink/swell up to 6.4 percent of its given width, depending on how it’s cut, when going from green (30 percent MC) to oven-dried.  

Averages = .00212

Averages = .90

Can be very challenging to work with due to its hardness, and gummy resins. Fasteners hold well, and there are no known issues with nailing purpleheart. Glues adhere nicely.

Moderately difficult and challenging to sand, and requires extra caution with grit progression. Do not skip grits when sanding this wood. The final pass normally is done with a higher grit abrasive than with other species. This wood finishes very nicely; however, the oils in this species can react with some finishes. Use of spirits or thinners can remove or lighten the purple color. 

This species is not listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendices or on the IUCN Red List of threatened species.
