DESCRIPCIÓN DEL ÁRBOL
Descripción botánica
Two sub-species with similar wood characteristics and distribution are reported, P. paniculata ssp paniculata and ssp pubescens. Some variation is reported according to the species, but it is often about 25 to 35 m in height, with a trunk diameter of abou
Distribución natural
This species is reported to be widely distributed all over Central and northern South America.
Usos No-maderables
The wood presents gums which affect wood processing.

Indice de Color (1= Negro, violeta; 7= Amarillo claro, blanco)
3
Grano
The grain is typically straight or wavy and sometimes interlocked.
Veta
Texture is mostly fine to medium.
Brillo
The wood exhibits a moderate to high luster.
Durabilidad Natural
The heartwood is resistant to decay fungi attack and to termites, but it is less resistant to marine borers.
Indice de Durabilidad Natural (1=Muy alta, 7=Muy baja)
2
Dificultad para impregnar
It is very difficult to treat, but for most applications preservative treatments are not required.

TRABAJABILIDAD
Aserrado
The wood is hard and it contains resins that affect sawing.
Corte de chapa rotativa
This species is interesting for slicing, thermal treatments are recommended.
Chapa tranchada
This species is interesting for slicing, thermal treatments are recommended.
Pérdida de filo_romado
It is considered to have a moderate blunting effect on the cutting elements.
Maquinado general
Peltogyne is reported to be moderately difficult to work in most machining operations including planing, turning, boring, and molding. They respond rather poorly to ordinary tools, and working with dull cutters may cause the wood to heat up.
Cepillado
A reduction of the cutting angle to 15 degrees is required, when wavy or interlocked material is present, to obtain satisfactory results in planing.
Torneado
30
Clavado
It has a tendency to split. Pre-boring is indispensable.
Encolado
The timber is reported to glue well.
Lijado
It is easy to sand.
Acabado
Organic solvents remove the characteristic purple color. To preserve the natural color, wax finishing is recommended.
Doblar al vapor
The wood steam bends fairly well.
Facilidad para herramientas manuales
Response to hand tools is reported to be only fair.
