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
