In Decking, Wood Species, Rough sawn


Dipteryx odorata (Aublet.) Willd
Other names:
Camaru, camaru-ferro, cambaru, cambaru-ferro, champanha, cumaru-amarelo, cumaru-da-folha-grande, cumaru-escuro, cumaru-ferro, cumaru-rosa, cumaru-roxo, cumaru-verdadeiro, cumbari, cumbaru-ferro and muirapagé.
General features:
Heartwood and sapwood distinguished by color, light brownish yellowish brown; moderate brightness; imperceptible smell and taste; high density; hard to cut; grain coated; fine to medium texture, attenuated fibrous appearance; slightly glossy surface.
Durability and Treatment:
Natural durability: the heartwood is highly resistant to attack by xylophagous organisms (rotting fungi and termites). In field trials with stakes in contact with the soil, this species showed high durability to xylophagous organisms and was considered highly durable with more than 12 years of service. It showed low resistance, in field trials, to marine xylophagous.
Treatability: impermeable to preservative solutions; the heartwood is not treatable with creosote (soluble oil) nor with CCA (water soluble) even under pressure.
Processing Characteristics:
Workability: cumaru wood is difficult to work with, but presents excellent turn performance. It shows poor finish in planer and sandpaper jobs, it is difficult to drill. Due to the oily nature, the wood presents difficulty in being glued. Accepts polish, paint, varnish and burnish.
Drying: It is relatively easy to dry in the air, with a slight tendency to superficial splits, it presents moderate warpage. Artificial drying is slow, but practically free of defects.
