DESCRIÇÃO DA ÁRVORE
Descrição botânica
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
Distribuição natural
This species is reported to be widely distributed all over Central and northern South America.
Usos não madeiravéis
The wood presents gums which affect wood processing.

TRABALHABILIDADE
Serrar ou Cortar
The wood is hard and it contains resins that affect sawing.
Desdobro da tora em torno para lâminas
This species is interesting for slicing, thermal treatments are recommended.
Desdobro da tora em faqueadeira para lâminas
This species is interesting for slicing, thermal treatments are recommended.
Desgaste de ferramentas
It is considered to have a moderate blunting effect on the cutting elements.
Aspectos do processamento em máquinas
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.
Aplainamento
A reduction of the cutting angle to 15 degrees is required, when wavy or interlocked material is present, to obtain satisfactory results in planing.
Torneamento
30
Comportamento na aplicação de pregos
It has a tendency to split. Pre-boring is indispensable.
Colagem
The timber is reported to glue well.
Lixamento
It is easy to sand.
Acabamento
Organic solvents remove the characteristic purple color. To preserve the natural color, wax finishing is recommended.
Steam Bending
The wood steam bends fairly well.
Trabalhabilidade com ferramentas manuais
Response to hand tools is reported to be only fair.
