Density (dry weight) = 38-45 lbs/cu. ft. 1 Density (dry weight) = 46-52 lbs/cu. ft. Max. crushing strength = medium Bending strength (MOR) = low Shrinkage, Tangential = moderate Shearing strength (parallel to grain) = medium Modulus of Elasticity (stiffness) = low Hardness (side grain) = medium Density (dry weight) = 53-60 lbs/cu. ft. Density (dry weight) = 31-37 lbs/cu. ft. Shrinkage, Tangential = large Shrinkage, Radial = small Shrinkage, Radial = moderate Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = very low Modulus of Elasticity (stiffness) = medium Bending strength (MOR) = medium
