Bending strength (MOR) = medium Max. crushing strength = high Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = low Shrinkage, Tangential = moderate Shrinkage, Tangential = fairly large Shearing strength (parallel to grain) = medium Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Density (dry weight) = 46-52 lbs/cu. ft. Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = very high Bending strength (MOR) = high Shrinkage, Tangential = small Shrinkage, Tangential = large Shrinkage, Radial = very small Shrinkage, Radial = moderate Shrinkage, Radial = large Hardness (side grain) = soft Density (dry weight) = 38-45 lbs/cu. ft.
