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