Weight = moderate Surfaces may dent or scratch easily Surfaces may dent easily Soft Max. crushing strength = low Hardness (side grain) = soft Crushing strength = low Compression strength (parallel to grain) = low Bending strength (MOR) = high
Bending strength in the air-dry condition (about 12 percent moisture content) is high - comparable to Teak. It is weak in compression parallel to grain (maximum crushing strength), and is inferior to Mahogany. The wood is soft, and surfaces may dent easily. It also does not wear well, and mars easily. The weight is medium. The wood is high in density.
