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