Very high density Exceptionally heavy Compression strength (parallel to grain) = high
The species has exceptionally high bending strength properties in the air-dry condition (about 12 percent moisture content). It is far stronger, for example, than Hard maple, White oak, or Teak. It is hard and superior to Teak and probably Mahogany. It weighs much more than Hard maple or Teak in the green or seasoned condition
