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