The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Compression strength parallel to grain in the air-dry condition is high. Teak, White oak, and Hard maple have high crushing strength. It is moderately hard and resistant to wearing and marring. The weight is high. The wood has high density.
