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