DESCRIPCIÓN GENERAL DE LA MADERA
Color
The sapwood is yellowish white to pinkish white, it has a thickness of 3 to 6 cm. The heartwood is yellow-brown to red brown, darkening on exposure, it is clearly demarcated.
Indice de Color (1= Negro, violeta; 7= Amarillo claro, blanco)
4
Grano
The grain is highly and systematically interlocked; special care is needed when drying because of frequent risks of distortion.
Veta
The texture of the wood is frequently coarse.
Durabilidad Natural
Very durable to decay; without preservative treatment. This species is especially suited for all the uses with risks of permanent or long-lasting humidification. Resistant to termites attack. Heartwood is resistant to Lyctus attacks.
Indice de Durabilidad Natural (1=Muy alta, 7=Muy baja)
