Max. crushing strength = medium Bending strength (MOR) = low Density (dry weight) = 31-37 lbs/cu. ft. Modulus of Elasticity (stiffness) = very low Shrinkage, Tangential = large Shrinkage, Radial = large Modulus of Elasticity (stiffness) = low Shrinkage, Tangential = fairly large Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = low Density (dry weight) = 38-45 lbs/cu. ft. Very dense Shrinkage, Tangential = moderate Shrinkage, Radial = moderate Modulus of Elasticity (stiffness) = medium Max. crushing strength = low Heavy Compression strength (parallel to grain) = high Bending strength (MOR) = medium 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. It is moderately hard and resistant to wearing and marring
