The TreeThe trees in Brazil may have reached an age of 200 years with a height of 18m to 30m and a diameter of 0.6m to 0.9m but on average the diameter is about 0.5m with a relatively short bole having a pronounced taper.
The TimberThe tree produces a light hardwood, weighing between 560 and 640 kg/m3 when dry. There is little distinction between sapwood and heartwood, the wood being whitish when freshly cut, becoming light brown in colour on exposure with a pink tinge. The grain is straight, the texture moderately coarse but even, and the wood has a sour smell.
DryingAlthough the wood dries rapidly, it requires much care : it should be anti-stain dipped immediately after conversion, and should be piled under cover, with closely placed sticks. There is a tendency for the timber to warp and bow, and top weighting of the stacks is recommended, as is end coating of the boards to avoid end splitting.
StrengthA strong timber, with strength properties comparable with those of oak.
Working QualitiesMedium to good - The wood is said to work easily, and to plane to a smooth finish. It tends to split in nailing.
