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