Bending strength (MOR) = medium Max. crushing strength = high Shrinkage, Radial = small Shrinkage, Tangential = small Hardness (side grain) = soft Density (dry weight) = 38-45 lbs/cu. ft. Shrinkage, Tangential = very small Modulus of Elasticity (stiffness) = low Bending strength (MOR) = low Shrinkage, Volumetric = small Shrinkage, Radial = very small Modulus of Elasticity = moderate Density (dry weight) = 31-37 lbs/cu. ft. Shrinkage, Volumetric = moderate Modulus of Elasticity (stiffness) = very low Bending strength (MOR) = high Density (dry weight) = 46-52 lbs/cu. ft. Density (dry weight) = 23-30 lbs/cu. ft.
