Very small
Shrinkage, Volumetric = very small
Mor/Bending strength = low
Modulus of Elasticity (stiffness) = low
Hardness (side grain) = very soft
Density (dry weight) = 31-37 lbs/cu. ft.
Shrinkage, Tangential = small
Shearing strength (parallel to grain) = very low
Max. crushing strength = low
The bending strength of the species is considered medium, being much weaker than White oak or Teak in the air-dry condition (about 12 percent moisture content). It is weak in compression parallel to grain (maximum crushing strength), and is inferior to Mahogany. It is of average, or medium, density.
