Density (dry weight) = 31-37 lbs/cu. ft. Density (dry weight) = 38-45 lbs/cu. ft. Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = low Max. crushing strength = medium Density (dry weight) = 23-30 lbs/cu. ft. Density (dry weight) = 15-22 lbs/cu. ft. Bending strength (MOR) = very low Bending strength (MOR) = low Shrinkage, Tangential = moderate Shrinkage, Tangential = large Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shrinkage, Radial = moderate Shrinkage, Radial = large Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = very low Hardness (side grain) = very soft Hardness (side grain) = soft Bending strength (MOR) = medium
