Dipteryx odorata
Cumaru (Dipteryx odorata) is a medium-hardness wood balancing workability and wear resistance, with a Janka hardness of 901 lbf (4008 N) and a density of about 0.87 g/cm³. It originates from south america.
With radial shrinkage of 5.4% and tangential shrinkage of 8.2% (a T/R ratio of 1.52), it is very stable in service, with low risk of cupping or distortion. Its fiber saturation point is around 25%, below which the wood begins to shrink and move as it dries.
