Compression strength (parallel to grain) = high
The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple. It is a heavy wood. The density is high.
