Density (dry weight) = 53-60 lbs/cu. ft Very high density Very heavy Compression strength (parallel to grain) = high Bending strength (MOR) = high
It compares favorably with Teak, which also has high bending strength. Some familiar species with high crushing strength parallel to grain include Hard maple, Teak, and White oak.It is exceptionally heavy, weighing much more than White oak or Teak
