Bending strength (MOR) = low Modulus of Elasticity (stiffness) = very low Max. crushing strength = low Density (dry weight) = 31-37 lbs/cu. ft. Max. crushing strength = medium Modulus of Elasticity (stiffness) = low Toughness-Hammer drop (Impact Strength) = very low Shrinkage, Tangential = moderate Shrinkage, Radial = small Bending strength (MOR) = medium Shrinkage, Radial = moderate Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = medium Hardness (side grain) = very soft Hardness (side grain) = soft Density (dry weight) = 23-30 lbs/cu. ft.
