Max. crushing strength = high Modulus of Elasticity (stiffness) = medium Bending strength (MOR) = medium Shearing strength (parallel to grain) = medium Hardness (side grain) = medium Toughness-Hammer drop (Impact Strength) = low Shrinkage, Volumetric = moderate Shrinkage, Tangential = fairly large Shrinkage, Radial = moderate Density (dry weight) = 46-52 lbs/cu. ft. Toughness-Hammer drop (Impact Strength) = medium Shrinkage, Tangential = large Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = low Max. crushing strength = medium Bending strength (MOR) = low
