Density (dry weight) = 23-30 lbs/cu. ft. Shrinkage, Tangential = very small Weight = light Toughness-Hammer drop (Impact Strength) = very low Surfaces may dent or scratch easily Surfaces may dent easily Shrinkage, Volumetric = small Shrinkage, Tangential = small Max. crushing strength = low Hardness (side grain) = very soft Compression strength (parallel to grain) = low Bending strength (MOR) = low
Bending strength of the species in the air-dry condition (about 12 percent moisture content) is considered low - much lower than Teak, for example. Maximum crushing strength, or compression strength parallel to grain, is low. It is weaker than Mahogany or Teak. The wood is soft, and surfaces may dent easily. It also does not wear well, and mars easily. The wood is light in weight. The density is average, or medium
