High in 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). Strength qualiIt is far stronger, for example, than Hard maple, White oak, or Teak. It is far stronger, for example, than Hard maple, White oak, or Teak. It is hard - harder than Teak, and does not marr or dent easily. It weighs much more than Hard maple or Teak in the green or seasoned condition
