Resists wearing and marring Modulus of Elasticity (stiffness) = very high Max. crushing strength = medium Heavy Density = high Crushing strength = high Compression strength (parallel to grain) = high Bending strength (MOR) = very high
The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Teak, White oak, and Hard maple have high crushing strength
