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