Bending strength (MOR) = high
Bending strength qualities of this species in the air-dry condition is very high, far superior to those of Mahogany. It has superior properties in compression parallel to grain in the air-dry condition than Teak, White oak, or Hard maple. It is moderately hard and resistant to wearing and marring. The wood is very heavy. The wood has high density.
